So I did a major swap in my 12v 47rh 94'. It is now a ppump 24v with a 4r100 :ford:. I am still using the stock wire harness and PCM. The only sensors I am still using is the tach, oil press, coolant temp, and TPS otherwise I completely deleted the wires all the way to the stock PCM plug. The stock trans part of the harness is still intact and tied on the side. The grounds, power wire, starting circuit, and the rest of the cab and truck harness is still stock. I am using a PCS controller for my trans, and need a tach signal. My dash nor the PCS will give me a tach reading. I completely unhooked the PCS controller and still nothing. I have checked everything, I had the whole harness in my lap checking for any damage. The tach sensor does not have any resistance between any of the wires, and I set the air gap to .049" and also tried .040". Still nothing! I just want to make sure I'm not missing something before I blast a $100 sensor at it for nothing! Is there any other tests I can do first?? Sorry for the novel, thanks in advance! :bang
