Trial and error on which phone cable is which. easy to do tho. unplug one--if the wall tstat goes dead that is the tstat wire. if not thast wire feeds the middle ac. Now, that plug is the remote sensor plug which you do NOT use. Your wall tstat is the temp sensor for that AC. The Middle and Rear units will have that wire connected to a wall temp sensor. What you have exposed, is exactly where the corrosion usually is. Odds are you have a defective cable cut or shorted. The BLACK phone cables connect to the Circuit board, the gray phone cables go to the Tstat or the middle AC. Doug
I don't know how you know these systems so well but I'm glad you do! Replacing the cable...can I tie it on one end and pull through or is it part of a bigger harness?
