Step 3: Route the Cable

For exterior routing (under RV):

1. Feed cable through the pass-through hole.

2. Protect cable with split loom tubing.

3. Secure every 12-18 inches with outdoor-rated cable clamps or zip ties.

4. Leave slack at connection points for vibration absorption.

For interior routing:

1. Remove trim pieces carefully using panel removal tools.

2. Feed cable behind kick panels, under flooring, or through ceiling compartments.

3. Keep cable away from:

• Electrical panels

• 120V AC wiring

• Heat sources

4. Use grommets when passing through interior walls.

5. Reinstall trim pieces once cable is secured.

Step 4: Install the Monitor

1. Choose your mounting location:

• Above the rearview mirror

• On the dashboard

• Replacement rearview mirror with built-in display

2. Ensure the position:

• Provides clear view of screen

• Doesn't obstruct forward vision

• Doesn't block any mirrors

3. Connect the video cable:

• Most systems use standard RCA connections.

• Commercial-grade systems may feature locking connectors.

• Route excess cable neatly behind dashboard.

• Secure with zip ties to prevent rattles.

Step 5: Connect Power

Monitor power connection:

1. Locate a switched ignition source (power only when vehicle is running).

2. Use voltage tester to confirm consistent 12V.

3. Connect using appropriate fuse tap or direct fused connection.

4. Verify total amperage draw doesn't exceed circuit capacity.

Automatic reverse activation:

1. Locate reverse light wire at rear light assembly.

2. Connect camera trigger wire to reverse light circuit.

3. Use proper splice connector for secure connection.

4. Test by shifting into reverse.

Installing a Wireless RV Backup Camera

Wireless backup camera systems dramatically simplify installation by eliminating video cable routing. Modern digital wireless systems provide reliable signal transmission well beyond typical RV lengths.
