P0342
I have a 90 jeep wrangler that I am installing an 03 5.3 4L60E, I have a Nelson Performance ECM, and it is setting code PO342, I have traced the problem to the fact that I do not have a 12 Volt reference signal from the ECM, the red wire from the sensor goes to pin 39 on the ECM connector and it is getting a ground voltage instead of 12 volts, My question is can I find a 12 reference on a different pin , or do i have to send the ECM back for repair, thank you
