'78 Wiring Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

BigRed · 01-27-2003, 03:47 PM

I just pulled a guage cluster out of a '78 and am going to put it in my '75. I have a '75 wiring diagram, but need to know which wires go to what on the '78 cluster.

Does anyone have a wiring diagram picture or can someone tell me which wires on the connector go to which components on the cluster? Or, is there some website that has a pic or diagram of the wires?

Thanks!

Scott when I added my aftermarket guages (cheapies) I followed Mike's wire setup here http://www.73-87.com/garage/gauges.htm and all were the right colors in right numbered slot. Should hopefully be close.
