I almost finished the EIS harness. I first did the wiring of some of the sensors (OAT, ammeter, manifold pressure...) before working on the EIS harness I got with the instrument. Some wires are not needed either because I don't need the attached sensor or because the sensor already has a wire attached. I marked all the wires.
The picture shows the EIS side of the harness and the Hall effect sensor for the ammeter.
