Circut board?

81pickup posted a thread about his gas gauge fluctuating, and he got a reply about a circut board possible short, My question is where behind the dash is it located?, I think I might have the same problem too.

Circuit board is attached to the back of the instrument cluster plastic pod.

You can buy replacement boards from LMC Truck parts catalog.

The circuit board I was referring to is the panel that the gas guage, speedo, amp meter, oil pressure, brake light and sometimes clock "snap" into. It's lime green, located behing the gauage cluster, the dash lights also go into this panel.
