Hi Adam. thanks for your expertise.
My Car used to have a ISC stepper motor that connected to throttle body. I now have a hypertune throttle body and I needed external IAC idle air control valve. I have a Bosch 3 wire and I used my exiting wire harness, 1 12v wire and 2 other wires I used positions where my stepper motor said aux 5,6 on ecu. I was wondering do I configure the IAC as a Solenoid or a stepper motor on PC link? I attached picture of IAC.
Thanks
