Here's the deal...I installed a b18c1 into my 99 civic Ex...the swap went fine. My problem is the wiring part. First, the engine wire harness did not match up with the stock harness. Second the obd2a p72 Ecu did not match the plugs with my stock wire harness. So what we did was remove the engine's wire harness and replaced it with one that would plug into to the firewall plugs. Then we used a 99'civic si Ecu to run my car so that i could drive my car home. Now heres the thing...I NEED TO INTALL THE OBD2A...but dont know where to start. I came to this forum cause i needed to hear what you guys think about it. What would i need to buy to plug in the obd2a into my car??
