I have pin numbers for the ECU plug but my resource doesn't tell me which connector into the ECU it is so I haven't been able to check the beginning of the harness to see if i'm losing my voltage in the harness or if the ECU isn't outputting a proper 5V signal.Any assistance would be appreciated,Thank you.</blockquote>
