Introduction & Neutral safety switch wiring

[matty_sunn1]

Hey,

After 6 long years I bought myself another cruiser. Back when I was 16 I bought my 1976 fj40 and brought her back to life (photos at the end). Loads of welding, parts, and some paint. But then I sold it, and had to move on from the 40 world, but always had my eye out for my next cruiser. Two Weeks ago I bought me... and the wife a 1993 FZJ80 and it has AC big plus over my old 40.

This weekend I had a chance to pull the engine to get rid of some nasty oil leaks and check out what I got myself into. Everything looks pretty good, except for one area. The Neutral safety switch plugs have had a bit of a ruff life from the po. It had been completely broken, 3 spliced wires and completely covered in rtv, clearly to waterproof it. I am looking for a pin out for the plug or a reason this may have been the route someone took with wiring... Also I will be soldering in a different plug.

Transmission end. Black wire has been run to "HEAD" relay Red/green wire, It does not have a matching wire on the engine side of the harness which doesn't seem right.

"Head" relay Red/Green wire going to black on transmission side.

Finally the Engine side of the plug

Some plug damage

The old FJ40

The New to me FZJ80

@matty_sunn1 I know this is an old post but did you ever find the pin out for the NSS? I’ve got the same issue I’m trying to fix. Thanks

Actually now that I’m looking at this the drawings don’t match the pin coloring listed. Pins 3 and 9 have an X meaning that they are not used by Toyota. Is this exactly what it should be and how was it verified. I just want to make sure this is correct

That’s how I wired mine up. It’s been several years since I did it and no issues.

Thanks! Super helpful. Just used this to fix mine. Magic moment to see the gear indicators all lighting up in the dash!
