I have 727 trany. Im trying to get the NSS to work for the starter ground and the back up lights. Tell me if I'm wrong, but the two outside pins are the back up lights, 12 volts in and out, and the inside pin is the ground for the starter relay ground? I've checked the hot wire to the switch and have 12 volts. I've checked the center pin and have no ground out when in park, and nothing between the two outside pins in reverse. Bad switch?
Thanks for the post, Tonyetony58@gmail.com
