    External IAC sensor wiring?

    Hi
    I have L77 swapped engine car with holley throttle body because of the performance ecu IAC sensor is not working how can I connect it with manually use switch.
    The sensor it self has if I remember right 5 pins
    Some cars have only three pins power, ground and signle but I don't know about this one
