Instrument cluster swap help???

[micscottj]

I need help on the wiring of an istrument cluster. I have a 74 model Chevy 4 wheel drive. I have aquired a gauge cluster out of an early 80's model 2 ton truck. The new cluster has a tach and small fuel guage.

The printed circuit on the two clusters is wired differently, so i have to rewire for the new cluster. Does anyone have a diagram or instructions?

I purchased a chiltion's online guide, but it is virtually useless. I also purchased a guide from eautorepaironline.net but they did not have my model, so i had to get the guide for an 83 model which apparently does not have the same color wires.

Please help.
