ESN-79731752 I did use quick serve this morning to find the two return wires come together for fan clutch and heater control valve. I will post what I found in the first post. Im kind of new to this ISX 15, I don't know if im on to something or not but I figured id give you what I got. Current codes I will post as soon as insite lets me back in.
