Neutral Safety Swtich wiring question

Okay, bear with me while I once again hit everyone here with the need for advice…and on a subject that I know has been asked quite often (but honestly I’ve not seen any definitive answers).

This may be a bit long winded….better grab a beer or two.

My 89 BKO had an AOD trans, it got fried and I have a nice C-6 that I am rebuilding, so I am going to swap it in with some other freshly rebuilt goodies (parts are all from my old 83 BKO, so I have the transmission, transfer case, cross member and drive shafts).

Now my problem lies in the NSS, C-6 and AOD do not share the same switch…or apparently the harness as well. C-6 NSS has four wires, AOD has 5 wires. So I started here by previously asking questions, never really getting exact instructions on what wire goes where…which is cool, since every project is different, so what one person does may not work for another (not whining…just stating a fact ).

Well today it was nice outside, I finally had sometime to myself and decided to investigate…so out I go with trusty Haynes manual, some paper for notes and the ambition to try and figure this out.

Now I think I’ve got it somewhat figured, but what I need is some confirmation and clarification on what I’ve figured out.

Here is what I saw (I pulled back protective covers to expose clean wires that were not faded to verify colors):

AOD NSS harness wire colors this harness is what leads into the electrical maze we call a wiring harness (and if I read the Haynes manual right, what they do):

Purple with Orange stripe = B/U lamps
Black with Pink stripe = B/U lamps
Red with Lt. Blue stripe = Ignition
Red with White stripe = Electric Shift Control Module *
White with Pink stripe = ???

* AOD’s aren’t electric shift though…so I am thinking that isn’t what it sounds like…but still part of the circuit that is needed for the NSS to only allow starting in the P or N position.

C-6 NSS harness colors: These are the colors on the harness section that goes from the switch itself on the transmission side to the plug that would connect to the harness above:

Red with Blue stripe
Black with Pink stripe
Purple with Orange stripe

So if I am thinking correctly, I should be able to splice the same color wires for the B/U lamps (Purple with Orange and Black with Pink) from the AOD harness into the C-6 switch and should have functioning B/U lamps…so long as all the other wiring after that is still in good shape.

As for the actually NSS, I would splice the Red with Blue and the Red with White (from the AOD) to the two Red with Blue wires from the C-6 switch, and should effectively have a fully functioning NSS switch, am I on the right track so far….or has my train of thought completely derailed?

And then there is that last wire from the AOD harness, the White with Pink stripe wire…I didn’t see any reference to it in the diagrams. I recall asking once before and someone said that one of the 5 wires is a ground to the computer. If that is the case, what do I do with it, just tape it off and tuck it away somewhere…or attach it to another ground wire somewhere else?

I just wanted to get some opinions here to make sure I am on the right track with my thoughts, I am much better at mechanical than electrical situations….but I am trying to learn! And I sure don’t want to start hacking my wires without knowing for sure.

So let me hear it folks…does what I wrote sound right, if not….HELP!!

Thanks!!
