10 Pin instrument wiring question

[doug_porsche]

Background info.

I bought an unfinished Gen 2 GTM.
I am reviewing what was done and doing what needs done.

My current rabbit hole is the dash/interment wiring.

Specifically, the 10 pin connector.

Can you either point me to where I can find the GM wiring diagram pin out for this
Or
If you say the wire that goes/is to
pin 1 white – instrument lighting
pin 2 black - left Turn Sig
Pin 3 purple – tach ??
Pin 4 drk blue – right Turn Sig
Pin 5 lite blue – left Turn Sig
Pin 6 black seems to be ground that terminates the led a pings 2, 3, 4, 10 7
Pin 7 orange 500 ohm resister tach
Pin 8 ??
Pin 9 is open
Pin 10 is blights.

Can you either confirm and/or let me know what it should be?
