I have a DX wire harness converted to MPFI and a 90 Integra B18A motor. I transferred the wire harness over to the integra motor, everything pluged right in, but on the Integra distributor it has a round 7 wire plug, but on my wire harness it has a square 5 wire plug. Is it because it's a automatic motor it has extra wires? The integra distributor has the round 7 wire plug and the round 2 wire plug for the sensor inside. Got a 1991 Civic Hatch. Any help???
