I'm putting a B&M shifter into my '67, and I'm trying to wire the back up lites and neutral safety switch into the new shifter. There's 2 purple 12ga wires running into the switch on the steering column with a pink and lt green coming out. The wiring diagram shows pink and lt green for both the lites and the safety switch, but I can only find the pink and lt green I just described. Not being an auto electric genius, I assume these are the neutral safety switch wires...the purple stay where they are and the pink and green go to my shifter. If I'm right about that, then where do I find the pink and lt green for the back up lites? Any "light" anyone can shed will be greatly appreciated. Thanks!
