My friend has a 2001 Mercury Sable with the automatic climate control. He used to have a deck in the car and now he wants to go back to stock and cannot find the RCU connector that he cut off when he installed his deck. We found one at the junkyard but the wires are in different pins and are different colors. Does anyone has the wiring digigram for both the RCU and the audio harness in the trunk? I was going to use the RCU adapter we have and add/change wire placements.
