Dash wiring questions

[oldsracer]

Does anybody have a picture of the wiring harness that goes from the boost/tach gauge in the cluster to the main dash wiring harness. The guy I bought the dash from so kindly cut the plug off but more of an issue is the wire colors don't match the existing harness or any wiring diagram I can find. Anyone have an idea?

Wires coming out of cluster;

Gray
Green

Wires coming out of dash;
Pink/Black

The tach module connector is located on the far right lower corner of the dash bezel. My be jammed out of the way by the previous owner.

Hahaha and know you know my confusion. I think I'm gonna go at it with a power source and see what gauges or lights respond to each wire.

So gotta give credit where its due, you figured it out. The bottom of the first picture has the same colored wires I have. A quick google search and it turns out its a calibrated boot/tach replacement kit sold by Caspers.Thanks again man!!!

Maybe this will help.
