1989 Auto Trans - Shifter Wiring Harness Schematic Needed
I'm installing an aftermarket shifter, and want to wire-up these circuits correctly. Can anyone help me out with either a scan from the shop manual for these connections, or provide a text listing of the wire colors and their interfaces (PWR / GND / starter / reverse lights etc..)? Thanks.

Yellow = Start signal FROM key.
Purple = TO starter motor. (May be grn/wht. Not positive).
dk blue = Hot in run or start = Power FOR back-up lights
lt green = TO back up lights
orn/blk = signal TO ECM that shifter is in Park or Neutral (used for Code 24 diagnostics, idle control, and EGR).
blk/wht = Signal Ground = Used for above ECM P/N signal.
