ok here is my quest. i took my car apart about 3 years ago, been working on it fram, eng, tran, body and got the body back on and doing elc. but on neutral back up switch. i got the two purples and the green wires and the 90 with three wires but i have a single pole that i don't have a wire for but a pink and orange that is for trans and i have a shift down cable. and i do have a 72 cutlass sup.

 

The purples are for neutral safety, greens are for backup. Also there should be a black and yellow that go to the seat belt buzzer (if your car has them - 72 was a change over year.)
If you have the TH350 tranny, the pink and orange plug just hangs.

 

I do have a th 350 and I taped up the pink and orange and I got the to purples and the greens I also have the seat belt sensor I am going to hook back up because my dad disconnected it a long time ago, but my main question is there one post all the way to the left that I have nothing to hook up to is it suppose to have a wire hooked up to it.
Thanks again
