Hey guys! i have a 1986 C10 that came with a 700r4 from the factory and i am trying to find the correct neutral safety switch. I have had my column in and out a ton and i broke the stock one. I have searched all over and am not able to find the same style one.

i tried searching the number on there with finding one one used one on some old website.

The replacement switches will have two or three extra terminals. Just install, adjust, plug in the connector, and go.

awesome thanks! this just functions as the neutral safety switch or reverse light switch?

I thought they handled both functions. Obviously yours only has one switch.

My 82 with the 700r4 had a 4 terminal switch that controlled the reverse lights as well as the neutral safety switch. It had two terminals on the left of your switch where the holes are "stacked".

I just looked at the 1986 GM Light Truck CK10-30 wiring diagrams.
The column switch just handles the reverse lamps.
There is no Neutral safety in the 1986 harness diagrams. The purple Circuit 6 wire goes directly from the CRANK terminal on the ignition switch, through the bulkhead plug, and on to the CRANK terminal on the starter.

The schematic is incorrect.

I just converted from auto to manual so I had all of that apart, and one of the plugs on that switch is the NSS even though it is not shown in the wiring diagram. This was on a 1987 R30.

The 1987 wiring diagrams have a NSS. They're a pain in the neck to read but it's there.
