i bought a new radio awhile ago and i just bought a back up camera that can b hooked up to the radio but i want it 2 come on every time i put the car in reverse so all i need to is where is the reverse wire and what color it is
If you mean the positive 12 volt feed wire that becomes live once you place the vehicles gear shifter into reverse that wire is at the back of the vehicle and runs to the back up lights , so trace the wiring and you'll find it.
If you open the trunk and locate the backup lights, the wires going to them will be your power source to them when you shift into reverse. In my experience, the wires are usually white, but you will need to look to be sure.
