My headers keep burning my speedo cable? It there a better way to run the 75" cable? Also, what color gear for the cable should be in the transmission with 3.73 gears? I have a reddish one. I think it is 19 teeth? I had a white one in but it was off and then the speedometer stopped working. It may have ruined the module where the cable is inserted? Any ideas how to fix this issue?
