Re: Can I put a 7 pod instrument panel in my 70 c10??

I have a correction to make to my last post ... for some reason, I was thinking 73+ when I wrote that description of the alternator wiring.

The 67-72 harnesses for warning light clusters have both a "GEN" light and a resistance wire connected in parallel. So when swapping to a gauge cluster, you can simply leave that resistance wire (usually brown with a white stripe) as-is in the circuit. It'll work with either an original externally regulated alternator or with a 10SI or 12SI internally regulated alternator.

The 73+ trucks with warning lights just have the "GEN" light so those years are the ones where a resistance wire or resistor needs to be added when converting to gauges.
