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
