I added a fiberglass topper with the rear keyless locking back door. It simply hardwires to my existing truck automatic lock wiring. The two wires are located in one of the 5 connectors just behind the drivers side kick panel adjacent to the emergency foot brake lever. It is supposed to be an orange and a purple wire. I tested two orange and a purple but it does not work. Does anyone know which connector and which 2 wires operate the truck auto door locks? Thanks in advance.
