I have a civic hatchback with a obd 2 gsr motor. When I wired up the engine there was no extra plug for the solenoid. I thought it was just an obd 2 sensor that was not needed. But come to find out it is more power that I am missing. So I need to find out how to wire this solenoid up to my ECU or do just wire it up to a constent power sourse with the key on. So I don't know where to start.
