In the process of installing the 66 chevelle tail light harnes in my 66 Beaumont. I have cut and mocked up the chevelle tail light harness but I am at a loss to figure out what all I need for the back up light set up on the muncie 4 speed. I have Summit Racing part number RP 20113 backup lamp switch extension and American auto wire 39504 back up light mounting switch. I believe I am missing one more wiring piece. Can anyone help with this? What am I missing here?
You need those plus an American Autowire 01993307 switch (or equivalent GM OEM number is 1993307, lots of choices out there). That switch along with the 39504 will mount the switch plus run the harness up to the firewall. The RP20113 harness is the one inside the firewall that you hook up to the harness that was originally plugged into your automatic neutral safety switch.
