Neutral safety switch wiring
Neutral safety switch wiring
I got a 1985 Camaro and I am in the process of fixing some wiring that the previous owner hacked up for some reason ( my guess is that he swapped the column out of a manual transmission car and didn’t have the proper ignition switch etc). I got the majority of the wiring figured out but am trying to narrow down were the yellow and purple wires go from the neutral safety switch to under the dash. The yellow was just dangling underneath and cut at both sides and the purple was cut at the safety switch with another wire spliced to a janky push start. Any help is much appreciated

Sorry to hear that. Previous owners are the scourge of the car hobby. Especially their lame attempts at "customizing" and "improving" the electrical system. Seems like the less they know about wiring, the more they get in a hurry to "improve" it.
The NSS depends on whether it's an auto or stick car. Cars come with wiring for both. In auto cars, it plugs into the shifter, in the console; in stick cars, it plugs into a switch mounted to the clutch pedal. The plug in the console also has the backup light switch wiring (small dark green and dark blue) and wires for a light.

OK, so it's an auto car.
You don't need the ones under the dash. Tape em up and stow em out of the way where no bare ends can touch anything else.
You DO need the ones in the console. Find the rest of them where the PO "improved" them with his dykes and un-"improve" them.
BAD BAD BAD BAD BAD BAD BAD BAD BAD BAD BAD. WRONG ANSWER no matter what the question is.
Not that there's anything wrong with Painless, as such; just, your car WILL NOT benefit from any more "improvements". It'll work ONEHELLUVALOT better if you UNDO all the hacking and just put it back like it belongs. Painless is for cars with NO wiring, and you're starting from scratch; NOT for overcoming PO hack jobs by adding more hack jobs on top of them.
Undo all the hacks that have been done. Reconnect the wires like they're supposed to be. Yellow to yellow, orange to orange, green to green, etc. etc. etc. NOT yellow to orange for example, as you photo shows; pink to pink and red to red, not pink to red and red to pink like that one shows. Like, I suspect that the yellow wire that's now spliced to the orange, BELONGS connected to the yellow at the shifter. Put it back RIGHT, find the purple, hook it up RIGHT too. Stop trying to "improve" on it further. You're already seeing what a rabbit hole that sends you down; STOP NOW while you're ahead.

I also got a painless column wiring kit

Re: Neutral safety switch wiring
I agree the only reason I did that was because one of the plugs for the ignition switch was totally missing and I couldn’t find anything better so I figured it is worth a shot. No clue why this guy hacked up a low km car with nothing wrong
Re: Neutral safety switch wiring
- As far as the yellow to orange goes that was some hacking that guy did for the radio , any wires that had been hacked other than those who have been connected to the appropriate wires .. thank god for shop manuals lol

Conveniently enough, GM is EXTREMELY LAZY about such things. Since EVERY model of car needs to turn on, start, etc., ign sw wiring, and the switches themselves, and even columns for that matter, are as near "universal" as they can be. After all, why make em different if they all do the same thing? I'd bet money that you can grab that plug off of just about ANY mid 80s GM car or truck, and it'll plug right in.
Again, a photo of what you've got would help with identification and so forth.

So I had a bit more time today and I got everything spliced back together I still have this purple wire and I can’t find what it connects to. I believe this goes to the starter solenoid but like I said I cannot see anything

Re: Neutral safety switch wiring
If this is under the dash, it's part of the NSS wiring for a stick car (the corresponding switch in those is on the clutch pedal) like I told you above, so you don't need it. cut the connector off, tape up the end real good, stow it somewhere safe along with the yellow one that also went to the stick NSS.
