I have a 2003 mercury mountaineer and put a 2002 mercury mountaineer hatch on it.The wiring harness for the 2002 hatch is different than the 2003 hatch. Would someone have the wiring schematic for the wiper motor and rear defrosters for both hatches so I can wire up the wiper motor and rear window defroster.
