I need help with guage wiring... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a '71 dash with only speedo and idiot lites and i want to swap it for a '72 full cluster dash but the wires are in different locations on the plugs. Is it as simple as matching colors and splicing the 72 plug to the 71 harness?

I haven't done the swap but here's a link that might help you.

Follow the instructions in Strokers link and you will be fine. All you need is a small pocket screwdriver to get the pins out of the connector. Do one at a time, relocating per the instructions.

I did the swap which means just about anybody can do it. I recommend finding a loom at the junk yard so you can practice on how to remove the pins w/o buggering them up too much.
