I accidently built the pre-2001 harness, the molex pins are different for the 2001-up gauge cluster. Unfortunately the guide I was using didn't mention that.
I'd be happy to sell it for my cost ($29). I don't like butt connectors, so I used solder and self sealing heat-shrink tubing instead. I used a label maker to number the wires, and a few zip ties to hold it together. Photo attached. I'll ship to lower 48 free.
