there is a buss block inside the dash behind and above the obdII port. I can't remember the wire colors but I think they are purple with black stripe and white with a black stripe. Tone the feed wire back to the firewall connector on the passenger firewall with an ohm meter. I spent the better half of a day on a friends truck after he spent hundreds on 3 mechanics and found one of the wires was broken inside the sheathing 1/4" away from the buss. He would have gauges and everything would be fine then at random the gauges would go haywire and sometimes some of the gauges would drop out all together. I was using a wiring diagram out of a factory service manual at the time which belonged to the owner so I don't have the diagram or I would dend it to you
