transmission swap - NSS ??

[swing69]

Can remember off hand what I did in the past. Oldtimers I guess!

The 65 trans has a single pin NSS, correct?

If so, when installing a later trans with a 3 pin NSS, how do you make the wiring change to keep the NSS functional.

If the NSS in in the shifter.....never mind this post. Man...I'm getting old.... thanks

The center post on the three pin switch is for grounding the NSS at the relay so the starter runs.
The two outside pins are for the backup lights.

There is a wire diagram around here somewhere I think.
