Thank you
Thank youPins 23 and 24 are the communications between the ECM and the gauge.
Maybe re-flow those pins and see if the problem goes away.
At least you found the problem. some of these electrical gremlins can go on and on.... :smile_old:It was the wiring harness. Everything is back together and all is well
there do u know how much should those pin messure? both are negative or ground ? I tested my harness and those 2 pins show less voltage than the other grounds. pin 12 should be a ground also?cos that one it not showing any signs.Pins 23 and 24 are the communications between the ECM and the gauge.
