Im posting this for my buddy. He has a auto 89 civic hatch. We put a manual 91 ls in it with the resistor, dizzy, ecu, hubs, linkage, and axles. we used the dpfi harness that came off the d15 and we wired in the injectors and the dizzy now we dont no about the other two blue wires coming from the dizzy. im pretty sure they are for ignition but dont know what to wire them to.
