I am unable to locate the wire for the back up light on my 4500. Trying to install a back up camera and need to find the reverse wire or back up lights. I have been told that it is light green. Any comments?
Thanks in advance
You can find that pin out in the 12 pin Body Builders connector along the inside of the right frame rail a foot or so behind the cab. Pin "L" is a Lt Green wire and is a back up signal just for your type of application.
Here is the link to the electrical schematics in the Body Builders Guide.
