You love your older car, but you envy the safety features of new models. The good news? You don't need to buy a new vehicle to get modern safety tech. Adding an aftermarket backup camera is one of the most practical upgrades you can perform.
While professional installation can cost $150+, doing it yourself is a manageable weekend project. Whether you chose a traditional wired system or a modern wireless backup camera kit, this guide will walk you through the process step-by-step.
Tools You Will Need
Before you start, gather these essentials:
-
Power Drill (if mounting to the bumper)
-
Wire Strippers & Electrical Tape
-
Digital Multimeter (to find the reverse wire)
-
Cable Ties (Zip Ties)
-
Panel Removal Tool (or a flathead screwdriver wrapped in tape)
Phase 1: Mounting the Camera
The first step is placing the "eye" on the back of your car.
Option A: License Plate Mount (Easiest)
Most modern backup camera kits attach directly to your existing license plate screws.
-
Remove your rear license plate.
-
Align the camera bracket behind the plate.
-
Screw the plate back on.
-
Pros: No drilling into the car body; centered view.
-
Option B: Bumper/Surface Mount
For trucks or vans, you might need to drill a hole in the bumper or above the rear doors to mount the bracket. Always check what is behind the surface before you drill!
Phase 2: Powering the System (The Tricky Part)
This is where most DIYers get nervous, but it’s simple logic. You want the camera to turn on only when you reverse.
-
Access the Tail Light: Open your trunk and remove the interior carpet liner to expose the back of your tail lights.
-
Find the Reverse Wire: Have a helper put the car in Reverse (engine off, parking brake ON). Use your multimeter to find the wire that carries 12V power.
-
Make the Connection:
-
Red Wire (Camera) -> Connect to the Positive (+) Reverse Light wire.
-
Black Wire (Camera) -> Connect to a clean metal bolt on the car chassis (Ground).
-
Note: If you have a Solar 3A Plus, you can skip this entire phase! It runs on a solar-charged battery, meaning you don't need to touch your tail light wiring at all.
Phase 3: Routing the Video Cable
If you bought a wired system, you now need to get the video signal from the trunk to the dashboard.
-
Snake the Cable: Run the video cable through the rubber grommet in the trunk (never crush it in the door jam).
-
Hide the Wire: Tuck the cable under the door sill plates and carpet edges along the driver’s side floor.
-
Up to the Dash: Pull the cable up behind the dashboard to where your monitor will sit.
Tip: This is the most time-consuming step. Using a wireless system eliminates this phase completely.
Phase 4: Setting Up the Monitor
You have two main choices for the display:
-
Dash Monitor: Mounts via suction cup to the windshield or dashboard. Plug it into the cigarette lighter for power.
-
Mirror Monitor: A rear view mirror camera clips over your factory mirror. It acts as a normal mirror when driving and turns into a screen when reversing. This offers the cleanest, "factory-installed" look.
Phase 5: Test Before You Close
Before you put all the plastic trim panels back:
-
Turn the ignition key to "On" (do not start the engine).
-
Shift into Reverse.
-
Check the monitor. If the image appears, you are good to go!
-
No image? Check your Black (Ground) wire connection. It’s usually the culprit.
-
