I have a 00' b18c5 thats going into a 96 ek cx. Which wiring harness do I need? I have the wiring harness from the b18c5 and also from the d-series. The driver side wiring plugs (comes from under the dash board through the firewall) doesn't match up with the c5 except for one plug.Also, would I need to buy an OBD2b to OBD2a conversion harness? Anybody have any pics of what plug goes into what plug?
