1989 Bronco NSS Neutral Safety Switch revisited

[mikefamig]

A while back I replaced my neutral safety switch and all is well with that but I would still like to get my hands on the wiring diagram for the NSS wiring harness in order to learn what each of the six wires does exactly.

Does anyone have a diagram that shows where each of these wires goes when they leave the switch? I would gladly share what I learn with the group if I can figure it out. To recap what I've learned so far, there are two wires for the backup lights, two wires for the NSS and two that are unknown.

TIA, Mike.

Yo Mike,

So I found a ford neutral safety switch that fits the C6 tranny and has six wires but I would need to buy one in order to figure out what each wire does. I would also still need a complete wiring diagram for the original part or even a working original part to reverse engineer the wiring.

Here is the part number for those interested:
