Searched on the help- bench harness tutorial info, and didnt find the info for the E37, wich are the pins needed on a bench harness for the E37..

im using 19-switched ignition, 20-battery, 73-switched ignition, 43 and 44 CAN signal on C1, on C2 73-ground, is this correct?? cant read a E37 ECM, maybe the ecm is bad. just want to check
