.color code for wire connector to center cluster gauge circuit sheet.

I am putting after market gauges in a c3 and have the following colored wires in the connector. #1 is black, #2 is dark green, #3 is pink/white,#6 is orange, #7 is dark blue, #8 is brown, #9 is black, #10 is tan, #11 is pink, and #12 is grey.
I know #6 is hot, #12 is the instrument lights, # 10 and #11 is gas gauge. There is no blk/wht for the amp meter, so I do not know which wire slot is for that gauge. It would be nice to know what the other colors are for so I may use them for something else. I have enclosed a url that shows the connector.

Thanks.

i have many wiring diagrams...  but can you narrow down the year...  it makes it a little easier for me to try to give you the EXACT answer..


your photos are kind blurry..  

 

i flipped open to the 77 model year..

on the  center cluster looking at the back of the cluster printed circuit...    reversed if looking at the front of the connector where its usually embedded in the printed circuit..    again.. this is for a 77.. as i just happened to have it up...

instrument lights/ ground
ignition / temp gauge
fuel gauge /seat belts
ground/  to the ? bulb under the seat belt bulb
alternator light/to the other side of the same ? bulb under the seat belt
oil pressure gauge/ constant power for the clock feed


blue will be oil pressure
green will be temp
tan is usually fuel gauge.. but it could also be straight pink on a corvette.
pink and black is ign.
orange is probably clock feed.
grey is instrument lighting.
yellow is the seat belts
brown is alternator wire
tan with a white stripe is probably the parking brake light circuit
please post a year..i hate to post the WRONG INFO..
