4L80E Neutral safety switch connectors
The tranny that came with my swap the connectors wouldn't come apart so the guy cut the harness. I cannot get them apart, seems like they are welded together. I talked to GM today and they told me its a common issue and you need to replace the switch, and both pigtails, and gave me a quote of $251 in parts. I'm okay with buying a new switch, but does anyone know of a place to buy new connectors or used ones that is not $112 and $45

4L60/80 parts are the same.
http://www.electricaladvantage.net/4l60e4l80emlps.aspx
The harness repair kit is listed on that same page, below the PRNDL switch. Total for all parts a LOT less then your quote. Hope this helps

Okay, I have overcome that hurdle in the build. I destroyed the range/neutral switch to save the connectors, but I have one small issue. The transmission came from a 2001, but my wire harness is out of a 99 as well as my pcm. Now, I have the two diagrams, but my question is do I need to have the second 7 pin connector hooked up running it as a standalone? There are no connections to the ecu, i believe it is only for starting and apparently reverse lights. Here are the two connectors, I already traced the four pin connector wires to the ecu, just wondering what to do with the second connector?

The connectors are glued into the switch, so dont feel bad
Luckily they're only needed on trucks, so cars and most swaps dont reuse them. Your PCM wants a P/neutral signal, so hook that to your shifter. Rest can be ignored
Swap harness will only have provisions for the P/neutral switch

I know, I'm bumping an old thread. But I've been trying to track down all the connector parts to build a harness from scratch (even tho I don't plan to at the moment) and I saw this post. I wondered why the plug I have seemed to have a coating of some type on it. Almost looks like dried CA glue. This makes a lot more sense.
Also, Thanks, Pocket. Your thread on connector cross references on 3rdgen was helpful in getting me started.

The glue in the '94-'03 Lucas neutral safety switches leaks out into the connectors from catalytic converter heat. The only upside to running this NSS is the high amp starter solenoid contacts.
I much rather have the '04 & up "Delphi" NSS! You just have to wire in a relay for the solenoid load (If this is a swap vehicle or a GMT400 truck).
In fact......If you don't have the engine in a '94-'08 GM truck or a '97-'05 Corvette....You don't need the trans mounted NSS. Let your shifter handle that if possible!

what I do is, goto junkyard and cut the wires. So you remove the entire neutral switch with plugs still inside it.
then simply re-wire it to your harness when ready. This way no fooling with glue.
figured it out after destroying two ofthem trying to get those plugs out. I thought it was a fluke the first time, "what the hell is this ****?!" but when I noticed they all had it I realized I needed a new plan. lol

Connector issues
Or you can use a heat gun...warm up the connector until the glue softens then unplug n replug without breaking anything or rewiring.....

I'm not carrying an electrical, battery powered heat gun into that place...
just cut the wires and run for yer life

I actually bought a switch and the pigtail ( I only bought one that has the reverse lights in it as that was all I needed it for in my application ) , off eBay and they worked just fine. Connector came with a good pigtail of the wires and nice connectors to make the connections with and heat shrink.

Well here I am bumping this old thread too. Does anyone know if can use just the backup light function of the switch. My swap harness doesn't even have connections for those wire packs. But I do need a backup light. Any suggestions?? Thanks much!

Scroll up to post #4.
Read the charts in that post...
Use the Light-Green wire (terminal F) and use the Black wire with the White tracer stripe (terminal D).

What exactly do you mean shifting the signal to the shifter and the PCM should be able to get its signal that it's in park
