U gotta send it some place like hasport or place racing cause the engine wiring harness of the b18a is ob1. obd1 harnesses are 2 piece, obd2 is 1 piece all the way to the ecu. What u do is have both the engine harnesses, then send it to them, they utilize some of the connectors and or add. Basically make it fit for your car. Why not just go with a b18b? And if ur using a cable tranny.......damn...
