E67 ECM in 98 C5
Hey all, helping a friend with a customer's 98 C5 in his shop.. The car has a GM LSX motor in it and when the install was done (probably 10+ years ago) the shop that did the install used an E67 ecm in it. They also installed a racepak IQ3 dash display as well. Big problem is the AC does not work, haven't dug into it too deep to see where each wire is ran for the pressure switch or anything else. My concern though is if the serial signal wire from the star connector from the hvac module can be landed on Pin 16 (connector X1) of the E67 and if it will recognize the signal, sending the relay its trigger. @Bill Curlee I hope maybe you can help on this one.
