Hey guys, new here. Im swapping a complete 90 1.6 powertrain into my 87 sammi axles n all. The wirings killing me! I want to run the fuel injection otherwise I would just plug into the old harness.Has anybody made their own harness out there? I wired up everything exactly by the diagram and not pulse to my ignition coil. The engine ran great when I removed it.Any help appreciated with the ignition side. A simple bare bones diagrams of ecm in and outs and ignitions ins and outs would be awesome!
