Another user mentioned this. Shift your tranny in reverse, and have your NSS ouf the post. Then, with something behind your taillights, turn the NSS until the reverse lights are lit up. Then you will have them matched up.
Did you say you don't have ignition? The NSS just prevents you from starting out of park and light up your reverse lights. If you are having a starting issue, that isn't your NSS

Could it be your NSS is ok and your ignition switch is bad? If the NSS IS ok (testing below) you can jump the two black wires marked B and C in the pic on the switch side of the plug. Careful, it may start in gear with the NSS disabled. If the NSS tests ok, then i'd look at the ignition switch, since the starter works when bypassing the ignition.

Well I fixed my crawling under my jeep to start it with a screw driver problem. I was digging threw a bucket of old tractor parts and found a push button switch that matched the color of my xj's interior. I just ran it from under the steering wheel to the two posts on my starter. Although it doesn't fix my back up lights it's better than $300.
