Pontiac Repair: 1990 firebird Hurst gear shifter replacement, reverse light switch, neutral safety switch

Question
hello I just recently installed a hurst V-matic 2 shifter in my 1990 pontiac firebird, 3.1L V6, 700R4 floor mounted shifter. I'm trying to find a schematic or a break down of the wires & connector that houses the neutral safety switch, reverse light switch, and gear indicator light. If you have any ideas it would be greatly appreciated, i've contacted GM dealers in my area and have been informed that their system does not have vehicles this old. Thanks in advance.

Hi Joshua:

They are right our online manuals only go back to 1998. send me another question the first part of the week and I'll look and see if I can dig out an old manual that will go back that far. I doubt it but I'll look. I work at a different dealership now and they were strictly Buick up untill last year when they bough the Pontiac dealership I was working at and I don't know what happened to the old service manuals.. But I will look for you....
