I'm swapping a B18A into my 2000 Civic CX hatch and I'm having trouble with the wiring. I have a distributor that came from a OBDII Integra. The plug for the distributor is not the same as the one in the Civic even though they are both OBDII. Can anyone tell me what each wire does on the distributor's harness and on the Civic's harness with their colors? And does anyone know why the Integra distributor have an extra wire? The Civic's original harness has 8 wires while the Integra's distributor has 9 wires. Thanks for the help.
