NSS Fix!
 

Yay! I did it! I was having issues with my reverse lights not working. I tried replacing the fuse in slot 11 in the dash fuse box and nada. All the research I did kept leading me back to the NSS. This looked like a meticulous, potentially disaster filled job. I was not confident. Then, I don't know, yesterday I just thought stuff it. Most of the tuts I watched had the NSS removed entirely with the ties snipped and the harness detached. That seemed like a lot of hard work. I decided to do the whole job under the truck. I just jacked it a little and slid underneath. Took a bit of looking around but i found the unit attached to the transmission on the DS. After carefully getting the unit off (it was really on there) I managed to open it up, clean up the gunk, sand the contacts, apply the dielectric grease and reattach it all under the car. Started first time and boom - reverse lights working!

Hi, Just another typical Jeep problem, seems like you lucked out first go. I find most of mine due to poor contact with the connectors, just close up the female side of the connector a little, a quick spray of contact cleaner then back together with a little dilectric grease around the plug seal and usually problem solved. learnt this after changing three TPS units to cure bad acceleration only to find the problem was in the plug, contacts needed closing up.

so many electrical gremlins in these old birds. I picked my XJ up for a song and it runs really well with 380 on the dial but OMG, so many electrical issues. Just this arvo I opened up the tail lights and found the previous owner had simply piggy-backed the wiring for the brakes, reverse and indicator lights for the trailer straight off the bulb wires. Sooooo dodgy. Oh well, just snipped them all off and rewired them back together. I don't need a trailer. Im slowly going through and finding lots of little things to do. But otherwise, great car!

hey wait on!..not dodgy, standard practice to overcome factory crap wiring

how else was I gonna make my trailer lights work!

haha, I'm sure your work is top notch! Im not saying the theory isn't sound, just the execution in this case wasnt great. haven't had any issue since I reconnected and sealed the original wiring.

took me awhile to work out what is a "NSS"

i still don't know ? but it might have something to do with your tail lights ?
