Thank you for the info the reason I’m trying to find out exactly as I’ve read on some of these forms about the 4–2 code fan clutch output (my fan is stuck on all the time )and I wanted to make sure the negative on ECU was the same which I believe somebody said was J1 pin 9
i’m checking volts today and continuity of the ground to the ECU
