I have a link g4+ for skyline GTT, I would like to wire in my AEM gauges/sensors. However I'm unsure where the AUX negative from the sensor needs to be pinned in to the ecu. The AUX 5V positive from the sensor needs to be pinned into a AUX on the ECU ( pin 104, 106, 107, 111, 117, 118, 5, 11, 13, or 17) correct? Also why are some AUX pins duplicate on the ecu? (AUX 1,5) sorry for my incompetence, i'm new to this.
