Looking to put a '97 STI engine (EJ207) into my '99 GC8/GF8 Impreza WRX. From what i understand the wiring loom is different and i was wondering the easiest way of making it compatible with the stock loom and stock ECU.
Thanks guys,
Ruben

(p.s sorry if this is in the wrong section or isnt clear, first time using a forum)
