Back up light wiring question
It looks like in the cars with a NAV radio there is a gray and yellow stripped wire that activates the camera when the car is put into reverse. My question is , does that wire exist in the wiring harness for the standard radios. If not , what is the easiest way to tap into the reverse circuit under the dash. I want to put a wireless backup camera in , but only want the LCD screen to receive power when the car is in reverse. Thanks
