Yeah the Lancers have a seperate ECU for the auto transmission as well and it lives on a metal plate bolted to the floor/firewall behind the cigarette lighter and under the fan box - real bitch of a spot :lol: . Thing is the auto wiring looms are made to suit the extra ECU and it can get pretty confusing very quickly once someone tries to rewire them. Best to just keep it plain and simple and grab a manual engine loom and ECU for sure - no headfuks or bandaid solutions so to speak. As far as differences between Auto and Manual ECU's in the passenger side kick panel are concerned I'll leave that for the ECU experts to explain as I've only ever sourced manual engine looms with ECU's.
