The reverse lights are also controlled via the NSS.

The purple wire on that connector is the output that connects +12V through to the starter solenoid (and the cold start injector).
If you jumper that purple wire to the battery +12V post, it will crank the starter. This bypasses both the Neutral Switch and also the Ignition Switch in the steering column.

This is a lot easier than crawling under the car to find the solenoid. I know, too late but it's worth knowing anyway.
That diagram is for an 86 V6 but it's probably the same for any year. The 4cyl diagram for 86 also shows it the same.
I was able to start my car this way when the linkage inside the column broke. But you still need to get it into the Run position. I could get it into Run, just not "Start". I think that's common.

On a manual, there should be a similar purple wire with the same function that comes out of the Clutch Start Switch. In that case you'd be inside the car so maybe there's a better place to get +12V from.

Many years back my neutral safety switch went bad. I was at the large Macungie PA car event, and very fortunate the car was parked on uneven soil. I put the car in neutral , put the ignitiom on and crawled under the car with a flashlight, reached back with a screwdriver and jumped the battery connection to the starter solenoid. The car started right up and we got home. This could be done on a solid surface by jacking the car up but never trust the car jack without using a jack stand. This experience was just pure luck.
