S13 IACV Wiring

[hks240sr20]

Hey I've been searching but I cant seem to find the info I need. Basically for the main connection on my harness by the battery where you have to combine the KA and SR harness's the black w/yellow from the sr side should goto black w/yellow from the ka, however I have no black with yellow on the ka side. I did have a yellow w/green I believe that was available with voltage but if I hook the Iac to it it goes from 12 volts with the key on to like 1.6. Anyway basically i'm lookin for a wiring diagram to tell me where the four wire harness goes off the IAC so I can trace them and see where the problem is. Or what I should hook the Black w/yellow to. Thanks in advance for any help.

Very strage to hear that the Ka does not have the b;ack/yellow wire. I don;t think i have ever seen a KA harness without one.

In any case, its possible that the Harness side does not have the B/Y wire, but the chassis side has it. Just doublecheck. It is located on the brown/copper plug

If you still can't find it, just connect the black/yellow wire to the RED wire on the GREY plug by the headlight. They are both constant power. No power draw will happen as the sensor is not grounded till the ECU is on.

Should work well.
