2 / tan with black stripe / brake warning light
3 / pink / +12V switched via ignition
4 / tan / fuel gauge sender
5 / empty
6 / dark green / temp gauge sender
7 / black / ground
8 / gray / cluster illumination
9 / dark blue / right turn indicator
10 / light blue / left turn indicator
11 / light green / high beam indicator
12 / black / ammeter (battery side)

The cavity numbers are molded into the plastic on the sides of the plug.

Most universal wiring harnesses probably won't have the provisions for the stock battery gauge (ammeter) wires that go to cavities #1 and #12. And the harness probably won't have the alternator output and main feed wires configured in such a manner to work with the stock battery gauge either. The easiest way to deal with that would probably be to convert to a voltmeter. Check with member TBone1964 ... he sells 76+ voltmeters that are modified to fit 67-72 gauge clusters.

I am a little confused. Reason being is I have found different diagrams that do not have the same Colors as my plug. I do not have a tach so I only have 6 holes on my cluster. Does that make a difference? If not do I still use the quoted reference to wires?
