FD3 idle control valve wiring
Hi guys, I am looking to rewire up an idle control valve on my 20b converted Fd3. However, I don't have wiring I place due to the aftermarket ecu. I can take a plug from an old 13b wire harness I have. I know one wire will be a trigger wire to my new ecu. Can some one verify if the other side is an ignition live or an earth. I cannot tell enough from The wiring diagrams I can find for the idle control unit and I must say electrics is not my strong point. All I can see is it goes off to a relay.
Thanks in advance.
Thanks in advance.

its the same switched black/white wire that does all of the other solenoids on the engine, so yes just ignition switched power, and then the ECU grounds the other wire
