It's kind of screwed up because I have a diagram and it doesn't show a neutral switch which I know it has on the steering column. I also have a wiring manual that covers years 67-71 and it doesn't show it either. So from looking at the harness as far as I can remember as well the red/blue wire activates the starter relay so one side has to go to I think it's far left connection on switch then the other would go to far right. Loop would go from park to neutral position. If you have one of those powered test lights you can figure this out by powering up the neutral switch at one pin then seeing where it goes via testing other pins like in park/neutral and you can find backup as well that is what I would do to get it correct.
