a few weeks ago i purchased an ae86 sr5 coupe. i have the 4age engine in it but wiring harness is cut up. im trying to find another one but none around my ny. im wondering if the mr2 harness the same? or from what other car it might be the same.

Have to have more information than that. For starters what version of 4age is it? Blue Top? Silver Top? Black Top? Red Top?

technically no other harness is the same. if you have money to spend (which I hope you do if your doing this swap) you can talk to tweakd performance and they can help you. not sure how much but my 20v harness was 550.

figure out which 4age you have. you'll have to do research to figure out which you have but it should be pretty simple to figure out. there's A LOT if small adds up expenses so be warned to budget carefully I did a gts conversion while I did my 20v and it costed more then I was expecting lets just say lol

any pics? if so you should start a build thread if you haven't yet, helps with all the question asking!

its a silver top motor.
