Hi everyone,
One of the things I am doing to my truck is replacing the gauge lights with LED's. It is cumbersome to place one, then have to put the cluster back in to verify that I have the positive and negative poles right. Does anyone happen to have a pin out on the cluster where it connects to the dash? I thought that if I could find the positive and negative poles, I could just put power to those outside of the dash itself to test the LED's for correct polarity.

Thought, suggestions?

Thanks, Dan

The dash connector plugs into the cluster through a flexible printed circuit. The printed circuit has grounds running though it to all of the pin-outs for the gauges and lights. if you trace the copper circuits to all of the lights there is usually a small + or - indicating voltage or ground.
Also if you do a Google on electrical schematics for your truck you will find a ton of them available for free just to download.
