I’ve been working away trying to wire up my ‘79 J10, ‘04 Tahoe LS motor/trans, Dakota Digital Dash, and Classic Auto Air. Seems like the right number of things to ensure disaster!
I recently got back to it after a couple year break and got tangled up with the swapped in Wagoneer auto column and trying to connect in the neutral safety switch. Confusion was taking over as I was struggling with wiring diagrams lack of detail in this area but there’s a happy ending here.
First,
Good info on NSS terminals here: https://youtu.be/ypZfyBf7Ta0
Second - I was trying to sort out the wires behind the dash so I could hook up the NSS and Backup lights parts of my newly installed neutral safety switch. I was a little worried about trying to track them from the ignition switch thru the mess of the column and harness. Since my truck was an original manual trans, I didn’t have a NSS and assumed I would not have the wiring or connectors so I had also reached out to a number of people with junk rigs. No one was willing go look for the connectors and they’re not available anywhere.
As I was tracing wires around I realized I had the wires and the connectors even though my J10 was a manual! They were both set up with little shorts across them ( not sure what to call them), tied up and tucked up high and in the far back. I pulled the little bridge things off and they plugged right in. Score! Maybe everyone but me knew this but it’s still a win! This made it much easier.

I swapped a ‘78 Wagoneer auto column into my ‘79 J10 as part of my LS swap. That brought with it the column mounted neutral switch.
I can run the wires needed but I need to know which terminals on the NSS to run them to. There should be a few for the NSS, a few for the Backup Lights, and a few for the trans kick down - 7 overall. I only need the NSS and backup lights.
Anyone know which terminals do what? Thanks!
PS - the OL Jeep and Tech Manual wiring diagrams don’t go to this level of detail.
