Hey Ive got an 89 crx with dual port fuel injection, but I have a fuel injected si engine that Im going to put in it. I know Ill have to get an ecu, but will I need to get a new wiring harness or anything? What ecu should I get? and what will need to be done to make this work? Everything will bolt up perfect, it's just the wiring that scares me! please help. thanks -Jeff

 

i know this sucker by heart! should be some unused wires at b2 and b11, move them to b10 and b12, cut c1 move it to b10, cut c2 move it to b12, run wire from c1 and c2 to the hf or si dizzy, c1 goes to blue green wire on dizzy and c2 goes to blue yellow, they are cylinder position sensor, cut a3 and a7 run wire from a3 to injector 2 and a7 to injector 4, take the yellow black on the right side of the harness to the yellow on injector resisitor box,exten tps and eacv, and swap the tps end wires or else ull be at wide open throttle instead of idle
