by BADBADGER Sun Aug 21, 2011 4:54 pmMy A727 has the old style single pole NSS in the tranny. The shifter has a two wire plug / pig tail, Wires are purple and white. Cant seem to locate them on the wiring diagram and dont know how to wire the NSS. Any suggestions? Thanks

the single terminal switch in the trans is for backup lamps only. the nuetral safety is on the shifter and goes to your starter relay .

Ok now I am totally confused! Is the switch in the tranny for the backup lights only? And does the two wires on the shifter go to the starter relay? My wiring diagram has no information on the shifter wires.

The single pole switch on the tranny is the NSS. The two pole switch shown in the wiring diagram is for the manual trans back up light switch. The wiring on the shifter is for the backup lights on the auto. Look at the front section of the Loadflight trans section in the manual and it shows both. The wiring diagram does not show anything on the auto but you should be able to figure it out.

Simple test, put the trans in reverse and see if the switch on the trans is shorted to ground or if its open with no connection to ground. If its shorted to ground its for back-up lights. If its open in reverse, but shorted in park and neutral then it is a neutral safety switch.
Another way to check is the 2 wires at the shifter, if one of those is powered it is for the back-up lights, as the neutral safety switch will always operate off of ground, never positive voltage.

No test needed. I pulled the info right from the manual. Section21-33 in the 68-70 manual shows the backup switch and the NSS switch. Doesn't show anything about the auto trans in the wiring diagram however. My 67 manual is out in the hangar and it seems like I remember a supplemental diagram of the back up and NSS wiring. I'll try to remember to look at it thia afternoon. Don

I just looked in the manual that Walker had posted up in another thread. On page 21-37 it shows a great big image of the Neutral Starting Switch (NSS) which is mounted on the transmission and has only 1 pin to it.

Finally got the thing figured out. Must be getting slow. The NSS goes to the stater relay. Engine turns over now. Got spark too.
