Need Speedo Advice
Ok so after much debate I finally swapped the trans in my '88 C1500 and got me a fresh TH350. I had a 700r4 in it at first tho. So now, I have a question. I've installed a speedo gear and housing with an electrical sender that's got 3 wires on the harness (black/white/red), but the harness on my OE speedo has only 2 wires (brown/yellow). So I was wondering, would I be able to cut the connector on the OE harness and just hook up the 2 wires to the 3 wire harness on the electric sender? If so, which wires would hook up to what? Thanks in advance for your help!
