I am trying to put air conditioning in an 87 MJ with 4.0. I have put an airbox from a 1993 XJ but the harnesses are not the same as the XJ. I have thought about adding separate wiring (homemade relays) but would like it to run though the ECM if possible? If anyone could share their experience and wiring schematic it would be appreciated. Also, I was wondering if the 6 wire plug before the heating harness is wired to the ecu? There are more wires going in then going into the 6 wire connected then to the old non-ac control. Would it be worth it to find a 1987-1988 XJ harness or can I get the 1993 wires to work? Than you for help, Scott
