Here is the plan:
There are 2 installation methods. Constant power, where you need to switch to backup camera when you want to use it, and backup power where the unit automatically takes over the screen when you place the transmission into reverse. The second is preferred, and involves simply tapping into the backup light circuit on the rear of the vehicle. The downside is that if you are pulling a trailer or just want to see what’s going on back there you cant use the camera while driving.
The solution of course is to add an in-dash switch/button to turn on the backup lights circuit while you are on the road. This can be a good thing since it will light up the area behind the vehicle to see what is happening, but could also get you pulled over under the right circumstances. Note that this is mostly just for fun on this vehicle since you would be hard pressed to find the towing capacity of this car, but should prove useful when I do the same thing on my wife’s GMC Envoy, and later when I add a 3/4 ton truck to the mix.
Read on to see how I accomplished this feat of engineering prowess.
