My s13 wiring harness is driving me crazy. I an going by what is on the FAQ page on heavy throttles web site. I am on the dash wiring and none of the wire colors match up. I am supposed to have a yellow wire with a red stripe for the tach, but that color isn't there. The plug from the SR harness doesn't match up at all with the KA harness. I dont know what is going and it is just pissing me off. Does anyone know what is going on? Please help.
