I bought a JDM B18c5 and have my old LS motor out of my Integra already. I have the wiring harness for the computer (OBD1 to OBD2.1) already. I am Having a major problem with the engine harness now. The JDM motor harness is ass backwards (because thats how they are built in Japan) and my LS harness has no hookups for the vtech and whatever else i need. My question is; Does anyone make another option for me rather than the $600+ USDM engine harness. If so what is it and what other sensors will I need. Please answer only if you are sure about this. I need professional advice. HELP :wtf:
