Re: wiring question 69
If you check out the sticky (Electical Basic) just above your post and look under 69 color schematics, bulkhead connector, it shows a 12 gauge pink wire going to the ignition. I don't remember that wire either in my install but maybe your harness could be for the transistorized ignition system that some 69's had. Thats just a guess though. Good luck.
