neutral safety switch question

ok, thanks steve. this I believe is a 71. so on the 3 prong connector that went to the 904 tranny I had in it, I guess I will take the outer 2 terminals and hook to the 2 prong switch on the 4 speed and what do I do with the center prong. does that term. go to the switch on the pedal or is it eliminated. is that one gnd. I noticed a wire that came out of the block on the firewall that I had marked as a neutral safety but didn't use it when I wired the car last time. will that wire now go to the switch on the pedal. I think it was a green wire. I will have to retrace the schematic again.
