So I spent the better part of the afternoon hardwiring a VR3 backup camera to my TT. Wired it into the wiring harness box for the hitch (in what appeared to be the wire for the running lights - I'm using it as a rear-view mirror instead of just for backing), ran about 75' of wire to the camera, drilled and mounted the thing, and now it doesn't work?!?!?!?!
There's power, it fires up, the screen comes on, you can see behind the trailer for a second, and then the screen goes blank!
I had tried it just simply plugged into the lighter socket in the car before going through the whole mess of running the wires and putting holes in my camper to make sure it worked. It did before!! Granted, that was only with a 25' extension as opposed the 75' I ran. However, VR3 says you can string up to 100' of wire, so I'd figured 25' short of that would be ok?
I may try a direct jumper to the TT battery in the AM to see if that works for a temporary fix??
Any ideas on what might have gone wrong?
