i have a 1990 civic hatch (ed6) im doin a mini-me swap im keeping my original 1.5 block and ima putting a 1999 1.6 ex head but i dont know how to do the wiring for the injector plug ins because my original obd0 harness doesnt have the plugs. if i get the 1999 ex harness it wont plug in to the obd0. i know theres a way to connect them to a resister box but i dont know how to do it. what do i do?!
