finally putting the pins into the blue and clear plugs. down to the last wire. it is a PINK wire from terminal "B" on the auto trans selector shift/range plug ?, can't find any reference to it ! there is a yellow wire on term B of one of the plugs goes to 68 blue, but cannot find anything on these GMTUNERS sheets about the PINK "B" wire. ( there are 2 plugs on the selector /range mechanism, don't know which is selector & which is range) HELP ! Thanks
The pink wire goes to an ignition on power source. It is the power feed to your backup lights. Pin f on the range switch is the blue wire that goes to your backup lamps, since the range switch is your backup lamp switch.
so, now I need to check the blue wire also. Am I correct that The RANGE Switch has nothing to do with the ENGINE Running ? Undoubtedly this wiring is the Hardest Part of the Entire Project, Thanks
