How to wire a backup camera to trailer wiring?
How to wire a backup camera to trailer wiring? I ended up tapping into the backup lights on the left side of the vehicle for power. And ran the signal wire into the repay box under the hood. It was a real pain in the *** tapping into the yellow trailer wire in the box as there was hardly any slack. I ended up having to use a quick splice which I didn't want to. But it worked fine. Where to find reverse wire for back up camera? Mine was a red and blue wire in the drivers side kick...
