Below is a copy of the 12 pin plugs for both gauges & idiot lights.
With the key in the RUN position you should have 12v at pin 7, the pink wire. Pin 10, green wire, is temp from engine, no power. Pin 11, brown wire is from gas tank sender, no power. Pin 6, Blue wire is for oil pressure light, no power. If you have power at pin 7, reconnect the plug to instrument cluster, with ign switch in the RUN position, disconnect the temp connector for the sender and ground it. The temp gauge to indicate full deflection. The same indication with the fuel wire grounded. The only time you should have power to the instruments is in the run position. I sure hope that this is helpful.

I have voltage to everything except these two guages. I unplugged the 12 pin connector that plugs into the pcb and checked for voltage there. everything is hot with the exception of temp and fuel. all my fuses are good. Any ideas.Thanks, Bob ----- Original Message ----- From: dhoesc...@granitecityperformance.com To: "The Chevelle Mailing List" <chevelle-list@chevelles.net> Sent: Monday, February 1, 2010 10:03:58 PM GMT -05:00 US/Canada Eastern Subject: Re: [Chevelle-list] wiring question
