The car is: 1968 valiant not stock. I put in a 392 with a 518/727 behind it. I'm wiring the car myself with a kit. I do not know where the three wires should go to from the neutral safety switch. Thanks for your help. Bill

Most of the schematics available are for computer controlled cars/trucks. I was able to find the info below.
This would lead me to believe the 2 outer pins are for the back up lights to go through when in reverse. The center pin sounds like a ground considering it says it should have continuity to the trans case when in P or N

Hope this helps
