The Beginners Guide to Backup Camera Installation

Originally posted on Feb 28, 2019

Looking to do your first backup camera installation? You’ve come to the right place.

This guide will walk you through the steps of purchasing, planning and preparation of your vehicle, and finally, the installation itself.


Please Note: This article is intended as a general overview and introduction to the process of backup camera installation. While we include specific step-by-step instructions with our products, be sure to follow the instructions for your specific backup camera model.

The process is straightforward if you’re a bit handy, read through this guide, and prepare. If you feel uncomfortable with the process most people can still save money by purchasing a kit and having someone more mechanically inclined install it, rather than taking it to the dealership.

The One Minute Explanation of How Backup Camera Installs Work

Every backup camera installation follows roughly the same few steps:

1) First decide which type of backup camera you want. There are many types of backup cameras you can choose from depending on your backup camera mounting options and rearview camera system power needs. You can choose between wifi models, or hard wired models (more reliable) that link up to an auxiliary screen. (We cover the pros & cons of wired vs wireless systems.)

We also have a wide selection of high quality OEM replacement backup cameras that will provide an equivalent experience to your current camera. There are also a variety of fancier DVR and integrated safety equipment you could choose from while you’re at it. Options with a wider feature set will of course run you more, but could save you thousands when dealing with insurance. More importantly, they will help keep you and your family safe.

2) Next, order your preferred backup camera, read the instructions, & prep your work area. For OEM like backup camera replacements you’re going to want to be extra sure you have the right model.

Broadly speaking, no matter what camera system you choose you’ll have to then do the following:

  • Depending on your chosen format for viewing the video you’ll need to either:
    • Install your selected monitor onto your dash or preferred location within your cab.
    • Remove your current rearview mirror and install the new unit you’ve selected.
    • Remove the panels necessary to gain access to your car’s head unit so you can wire your camera appropriately or install your wifi interface module.
  • Then you have to run the cables for either power, trigger wire, or video feed (depending on your configuration & monitor) to the back of the car.
  • Afterwards, you have to mount and install your backup camera in your chosen location.
  • From there you need to decide on your ideal way to power your camera, by either hooking up to the reverse light power (most common but this provides the least weather resistance) or powering with a connection in the cab.

3) You should then be able to test and make sure everything is working as intended. In most cases you’ll want to be sure the system is fully installed before testing your install.

 

Backup Camera Installation Costs

If your camera has bitten the dust, you’re likely asking yourself: How much is it going to cost me to replace a backup camera?

The good news is that with an installation like this, any handy person will likely already have most of the necessary tools on hand, and we provide useful extras in our kits like ties and tools to pry parts off.

Backup camera installation cost is often entirely dependent on you. The units themselves can range in price from:

As far as time goes, you should budget between 1 to 4 hours to install your backup camera. Your experience and the complexity of your chosen system really determine how long it’ll take. Obviously you don’t want to rush.

Let’s get going so you can see how to plan the installation.

 

Plan for Rear View Camera Installation Success

Listen, this isn’t going to be as simple as it is to backup your camera roll. You’re going to need to think about how you’ll route these cables through your car, and get your hands dirty.

But having a good plan is going to go a long way.

First, you need to decide where you’re going to want to look to see this backup camera.

Installing a display in your dashboard or radio console is a whole different kettle of fish, one of which we will address in a later guide.

For the purposes of this example, we’re going to assume you’ve acquired a rear view mirror kit or one which you can mount on top of your dashboard or to your windshield. There are advantages and disadvantages to both, so we won’t advocate for either here. However, we do recommend that if you’ve bought a kit, use the monitor that comes with it, as that will make things much easier.

Next, you have to ask: Are the provided cables long enough for my car? It’s better to have too much than too little, because you can always trim it down or secure extra wire. With too little wire, you might find yourself out of luck right in the middle of a project. Make a rough measurement from where you’re going to place the camera back to your trunk/license plate area. That will roughly correspond to what you need, and make sure you have a few extra feet just in case. All of which is to say, make sure your chosen kit will actually fit in your car, truck, or SUV. While we include plenty of high quality wire in our kits, you can typically tell a low quality backup camera kit by how much thought went into the connector wires quality.

Before you get started you’ll want to read and reread the instructions. Installing a camera should be painless if you know what you’re doing, and have familiarized yourself with the process.

And with that, you should be ready to start your installation. Next, we’ll move on to how to install the backup camera.

 

Sample Wiring Diagrams

Below is an example of what most backup camera installations look like when using monitors:

This is the most common configuration for wired backup camera systems. In this setup, the camera is installed near your license plate or rear bumper. From there, the power cable runs to your reverse light wiring, so the camera only powers on when you put the vehicle in reverse. The video cable (usually RCA) is routed along the interior panels of your car, under the carpet trim, headliner, or door sills, all the way up to the monitor mounted on your dashboard or windshield.

You may also have a trigger wire running from the reverse light to the monitor. This wire tells the monitor to switch to the camera view when the car shifts into reverse. Some monitors auto-detect the video feed and don’t need a trigger wire, but others absolutely do. So check your manual. This layout keeps everything neatly tucked away and works well for most cars, trucks, and SUVs.

Below is an example of what most backup camera installations look like when using rearview mirror monitors:

With this setup, the monitor is built into a replacement rearview mirror. This mirror often has a built-in screen that activates when the camera is triggered. The wiring here is nearly identical to the dashboard monitor configuration, except the video cable routes through the headliner and over to the mirror instead of down to the dash.

Power for the mirror typically comes from the fuse box or can be tapped from the dome light wiring, depending on the model. If your mirror has buttons for brightness or settings, make sure it's getting proper voltage. And yes, the reverse light is still the most common trigger and power source for the camera, but for more advanced installs, some prefer tapping into ignition power and using a switch.

Below is an example of what most backup camera installations look like when using OEM fit components.

OEM-style systems are a whole different ballgame. These are designed to integrate with your factory infotainment system, which means less visible equipment and a cleaner final look. But it also requires a deeper understanding of your vehicle’s wiring.

Typically, the camera fits directly into the tailgate handle or a designated slot in the bumper. The wiring may already exist in your car if it was pre-wired from the factory. If not, you’ll have to run power, ground, and video wires through tight factory channels and grommets. These setups often need a specialized interface module to ‘talk’ to the factory screen. That means fewer aftermarket components, but more complexity in getting everything to sync properly.

In some vehicles, accessing the head unit involves removing half the dashboard. You’ll want trim removal tools and plenty of patience. But once installed, it looks and feels like it came straight from the factory. Just be prepared to do a little more sleuthing with your multimeter and wiring diagrams.

 

Assemble Your Tools and Equipment for Camera Installation

For your tools, you’ll need a power hand drill, an appropriate bit for drilling holes to feed cable, fishing tools can be helpful, and the right size rubber grommet (a cylinder of rubber that will protect the cables from being damaged by the sharp metal edge of the hole you’re going to drill). Ties can also help keep things secure.

Your backup camera will likely come with the necessary cables (usually camera and monitor female/male RCA cords with connectors for video, power cables, ground wires, and potentially a trigger wire). If not, you’ll probably need to purchase these, and most can be found at a hardware or A/V store. Finally, a crimper or wire stripper will be useful to have on hand.

Every car and camera kit will be a bit different but generally speaking you should be covered if you have the following tools on hand:

  • Hand drill with drill bits for drilling metal (preferable high speed bits coated with titanium oxide)
  • Torx set
  • Wrench Set
  • Safety Goggles
  • Flashlights
  • Standard wire stripper/crimper
  • Torx socket set
  • Razor knife
  • Socket or nut runner set
  • Trim removal tool or small plastic putty knife
  • Soldering iron and solder (optional)
  • Shrink tube (optional)

Finally, if your kit didn’t come with one, you’ll need to purchase a monitor, but it helps to figure out the next step before doing so.

 

Sample Installations

We’ll include a general walk-through of an install here, but you can also check out some of our specific product guides for installation.

Install Example for a Backup Camera with a Monitor

Your backup camera is most likely going to be installed just above or on your license plate. We’ll start there. Here’s what to do:

  1. Remove the interior panel of your trunk. This is likely hard plastic or rubber, and you should be able to use a tool like a flathead screwdriver to pry it off. This won’t break anything, and it will give you a good look at all the cables necessary. Most things can be finessed out, if you’re snapping plastic you’re getting too aggressive during the install.
  2. Remove your license plate.
  3. Making sure you’re not going to cut any existing cables, drill a hole from the exterior side of your trunk that will be large enough to run the necessary cables through. You’ll add your license plate back later, but it’s a good idea to make sure that if you’re going to be installing the camera over the plate that you won’t be blocking your license plate number.
  4. Insert the rubber grommet you bought earlier. Now you’re ready to start running and connecting wires.

Running and Connecting Wires

Here’s where we start to figure out how to power a backup camera. Let’s go!

  1. Run the camera and power cable through the hole into the interior of your car.
  2. Locate the reverse light wires for your car. This is a tricky step, and you want to make sure that you do a good job. This is how to connect a backup camera to the reverse light. Make sure to double check your owners manual to ensure you’ve located the right one.
  3. Strip the positive and negative wires on your reverse lights (make sure your car is powered off before you do this). Using a small screwdriver, separate some of the strands of the stripped wire, and splice in the power cable for your backup camera to them. Usually you can do this by looping the wires together. Make sure positive is connected to positive and negative is connected to negative. Once you’ve done this, cover everything in electrical tape.
  4. Connect the RCA cable to the camera’s cable, and run it all from the trunk to the fuse box area at the front of the car. This is usually located to the bottom left of the steering wheel. You can conceal the cable underneath the ceiling panels of your vehicle if you want to peel them back, or if you don’t care about aesthetics, just attach it to the ceiling of your car.

Mount the Monitor

  1. The next step is mounting your monitor. It may be one that mounts to your rearview mirror, or one that mounts to your dashboard. In either event, following the mounting instructions that come with the device is your best bet. If all else fails, this backup camera installation guide can be very helpful.
  2. Connect the RCA cable to the RCA output on the monitor. You may also need to run a trigger wire up to your monitor, or even power it through the same source as the backup camera. (Again models will vary.)
  3. If the monitor requires it, you’ll likely need to install a fuse tap, which will allow you to connect the bare wiring of your monitor to the power of your fuse box. See the guide linked above for good instructions on how to do this.

Mount the Camera

Get excited, because we’re on the home stretch. All you need to do now is mount the camera itself to the back of your license plate or trunk, connect the appropriate wires (RCA and power) and you should be ready to go!

 

Testing Time

Time for the dry run. Before you reassemble everything in your car, run some different configurations of driving conditions to make sure that the camera is functioning properly. Put your car in reverse to test and make sure that the camera is powering on when it is supposed to, and also test your brakes to make sure you didn’t wire the camera into the wrong cable (you don’t want it coming on every time you pump the brakes).

If you encounter any issues you might want to reference some of our basic support guides like:

Common Problems and Fixes

Camera Won’t Power on

  • Check your connections: Make sure your camera’s power wires are attached to the correct vehicle wires (typically the reverse light positive and ground). If wired incorrectly, the camera will not receive power.
  • Recheck fuses: If your camera or monitor isn’t getting power at all, check for a blown fuse in your vehicle’s fuse box, especially if you used a fuse tap.
  • Test with a multimeter: Set your multimeter to DC volts and check for voltage at the camera’s power wires when the car is in reverse. No voltage? Retrace your wiring steps or test from an earlier point in the circuit.

Poor or Flickering Image

  • Inspect video cable connections: A loose or partially plugged-in RCA connection can cause static, lines on the screen, or intermittent video.
  • Double-check polarity: Switch the power connections if you suspect a mix-up. Incorrect polarity can prevent the camera from powering up or cause poor performance.
  • Ground issues: A weak ground can lead to noisy images or erratic operation. Ensure your ground wire is securely fastened to clean, bare metal.
  • Test with another monitor (if possible): This helps isolate whether the issue lies with the camera or the display.

Blurry or Foggy Image

  • Clean the lens: Sometimes, the simplest solution is just to wipe off moisture, dirt, or plastic residue from the lens.
  • Check for condensation: There could be moisture inside the camera housing. Verify that it’s properly sealed. Some entry-level cameras aren’t fully waterproof; consider a replacement if needed.

General Troubleshooting Tips

  • Retrace your wiring path: Loose, pinched, or damaged wires are a common source of trouble, especially near door hinges or where wires bend.
  • Secure all connectors: Make sure every plug “clicks” into place and no pins are bent.
  • Reconnect all wires: If all else fails, disconnect and reconnect every wire to rule out a poor initial connection.

If you’re experiencing problems, double check the manual and remember that most problems in environments like this come from bad wire splices, bad connections, or not tying off unused power cables.

Start there, and continue to troubleshoot until you have a functioning backup camera! Test your system before fully reassembling interior panels so you can fix any issues with easy access.

 

FAQ: Common DIY Questions about Backup Camera Installation


What if my camera flickers or the display keeps turning on and off?

Flickering often means a loose RCA cable or power connection. Check the cable seating at both ends, and ensure you’re using clean, undamaged connectors. If it’s a wireless system, try moving the transmitter or checking for Wi-Fi interference.

Can I install a wireless backup camera myself, or is it too complicated?

Absolutely. Wireless cameras are often easier to install because you don’t have to run a long video cable through the vehicle. Just mount the camera, connect it to power (usually the reverse light), and sync it with the monitor. Read your kit instructions carefully for pairing steps.

The image is reversed/mirrored. Is something wrong?

No, reverse or “mirror” image is normal for backup cameras, so objects in the camera view move the correct direction on the screen as you steer. However, if your camera has a switchable image setting or “mirror/normal” wire, double-check that you haven’t accidentally set it to the wrong mode.

How do I update my camera system?

If your current system is outdated, upgrading may involve replacing the monitor or switching from analog to digital components. Check compatibility with your vehicle's head unit, and consider systems with HD resolution and better low-light performance.

Do I need to drill into my car?

Usually, yes—but carefully. You’ll likely need to drill a hole to route the camera wiring from the license plate area into the trunk. Always use a rubber grommet to protect the wires and prevent rust around the hole.

Can I connect the camera to something other than the reverse light?

Yes. Some users prefer connecting to a constant power source so the camera stays on. However, this may require a manual on/off switch and careful routing to avoid battery drain.

Will installing a backup camera affect my car's warranty?

Most basic installations using plug-and-play kits or adapters leave your vehicle’s factory wiring untouched, which generally preserves your warranty. Splicing into factory wires is riskier. Consult your vehicle’s warranty terms, and consider professional installation or OEM integration kits if you’re concerned.
