I didn't realize that the rebuilt 727 I installed in my D100 project is an early model. G2538334. It has a single pin neutral safety switch. I haven't pulled the pan but, I'm guessing the builder didn't swap the rooster comb or the VB. I was hoping to add backup lights when I rewire. I guess I'll have to add a switch to the shifter? The shifter is a Lokar which has a neutral switch on it. In my search, I couldn't determine if it can be used for backup. Any suggestions? Resolved! Here is how I did it. The single pin on the trans will work for the NSS as designed by ma Mopar. No modification to rooster comb, switch or VB. I'll just add the later starter relay. On the Lokar I adjusted the NSS opposite of the instructions. The switch now has continuity while in reverse and neutral. I'll add a relay so the amps won't pass through the switch. It has an open in P,D,2,1. I could modify the shifter comb to remove the short while in neutral but. who cares.
