Which pins on ECU get power from the ignition?
Hey,
Does anyone know exactly which pins on the ECU get power from the ignition switch? Trying to figure out how the ECU gets powered up when the key is turned on.

Thanks,
allen

What about pin 20? Looks like it needs juice when the key is in start mode.

I think there's actually an ECU relay that supplies power to it, have to check the FSM. Be careful messing around there with the ECU pins, shorted ECU pins can seriously ruin your day
