i bought a 2000 acura integra gs that had a partial vtec motor swap. it originally had a non vtec motor and a b18c vtec was dropped in. they told us the harness does not work with the motor and the motor did not come with its harness. we are curious as to what to do in terms of wiring. there is a lot missing and we have to figure out cooling and vacuum systems but our main concern is the engine harness and finding the right ecu. they told us it was either from a 95 or a 98 car but it looks like an obd2 motor. any help would be much appreciated. thanks all.
