Is this normal?

I installed a used harness from the junkyard in my 73 hiboy. I noticed when I rev the motor the cab light gets brighter. Is this normal?

Probably not. I mean, no. But mine does that, too.

Was the junkyard harness out of the same year truck. I put the wrong year harness in a truck once and the gauge would flutter, don't know about the cab light since I never got around to fixing that. I added a quote from NumberDummy showing the different harness.

Several factors to consider - age of harness and condition of wire; flaky ground somewhere; alternator output; etc...

Anything else except the cab light affected?

Not sure if anything else is affected, since my carb is preventing me from actually driving the truck.
