Back up and Side View Camera Systems

Good deal. I cussed, kicked and moaned for a couple days trying to figure out why mine didn't work. Checked the monitor and camera off a battery and they worked fine but hooked to the reverse light I got nothing. Never heard they were using dirty power to run the lights in some newer rigs until I found a reference to it somewhere on the net and decided I needed a new power source. Of course the trailer plug wiring isn't the same color wires as on the truck so I spent a half hour laying on my back under the truck trying to figure out which wire powered the trailer reverse lights. In hind sight I should have just wired the camera into the running lights then I could switch to it while towing if I ever want to look at the trailer tongue.
