Idle Control Valve wiring diagram
 

Does anyone have links to 45/ZS wiring diagrams or know what each wire on the IACV on the 4 cylinder K-series is for? Having trouble with the 1.8T not idling right and I'm trying to rule out any wiring issues as the IACV has been changed twice now and still no change

Thanks in advanced guys

There is a wiring diagram on www.the-t-bar.com for the K series. Although it's actually for the MGTF the wire colours should be the same and they connect in the same way.

You will have to look for downloads under the community tab at the top of each page.
