This plug-n-play harness is for the 93-5 Mazda RX-7 FD3S. You simply connect power and ground with the red and black terminals, then plug the harness into the factory ignitor connector , and connect the labeled coil connectors to your IGN1A or AEM Smart Coils (30-2853). No need to cut and splice, etc. Just connect power/ground and then plug the connectors in.The harness has a built-in relay and fuse, and uses 10awg wire. I will include suggested coil dwell settings for both PowerFC and other ECUs. We have a Youtube video to guide you through installation. Search Youtube for "DriftinJim IGN1A" and the two videos will show up. If you are looking for a complete upgrade kit including harness, genuine IGN1A ignition coils, coil mounting bracket, and NGK spark plug wires, then look at my other auctions.
I offer a bolt-in kit for both the cruise control location and the frame rail.
