1967 GTO Gauge Wiring Diagram

[Johnny C.]

I am looking for a wiring diagram of 1967 GTO Rally gauges. Does anyone have one or know where I can find one? Does anyone know how to wire up these gauges with a Painless wiring harness? Thanks for any help guys.

Anyone? I just need to know which post on the back of each gauge is the sender, power, and ground. Can anyone help?

Your best bet would be a factory service manual, or a restoration guide. Are you using a Painless setup? If so, should be wire to wire. If you're using factory harnesses, there's a rally gauge extension harness that is used for the gauges.

The gauges are electric, so, one side of the gauge gets power, the other goes to the post on the corrosponding sender.

I am using a Painless harness. I have a factory service manual on its way. I am just wanting to make sure I have things right before putting the dash in because it is a pain to take in and out. I understand what you are saying and that helps me out. Thanks.
