k... in theory
the 90+ 7mgte ecu will have the same type of plugs as a 1jz ecu does
cut them from a 90+ 7m harness and rewire onto your 1jz harness as it will need extending if you are lhd anyway. check out
www.1jz-gte.us for ecu pin info.
when you go to buy the engine just ask them if it has the engine mount brackets. if not i guess you'll have to post in wanted forums and search ebay etc
