I have a Z3 with a backup camera that working fine when I put the truck in reverse. I tow a 5th wheel so I mounted the camera on the back of the 5th wheel and it works fine when I put the truck in reverse. I want to tow a trailer behind the 5th wheel, I would like to have a switch in the truck to turn on the camera at will, so I can see the trailer while I'm driving down the road. Can you halp me with the mods I need to do in order for this to work?
Thanks for your help in advance...
