Cam Kostek Posted September 4 Report Share Posted September 4 Hi all! I am currently taking on the task of constructing my first wiring harness for a sr20det. most of the planning phase is done and I have been using links A/B flying lead looms to make the harness. One thing I've been a little confused on is how to wire the IACV. Most posts I've seen only go over s14 IACV with the 2 separate solenoids and connectors. currently I am using the AUX 1/2 for Iacv open and close and will be running +12v to the sensor. with my research I've seen that some people only use one wire for IACV open and 12v, so only 2 wires to the 4 pin connector. I'm just trying to find out what the best way to do this is, and how others have. Id like to retain the stock use of the IACV, but don't need the second solenoid that helps for extra loads like AC. Thank you! Quote Link to comment Share on other sites More sharing options...
Vaughan Posted September 4 Report Share Posted September 4 Do you have a picture of the iacv you are trying to use? Quote Link to comment Share on other sites More sharing options...
KennyJ Posted September 5 Report Share Posted September 5 the hex shaped part is the airco idle-up , you dont need that the other wires are the idle solenoid , use 12v on 1 wire , auxilary on the other the mechanical screw works extra on the range of the electronic part--you should be able to make it idle perfectly on 0% duty on the electronic valve Quote Link to comment Share on other sites More sharing options...
