    Fault codes Errors

    Hi Adam. thanks for your expertise. My Car used to have a ISC stepper motor that connected to throttle body. I now have a hypertune throttle body and I needed external IAC idle air control valve. I have a Bosch 3 wire and I used my exiting wire harness, 1 12v wire and 2 other wires I used positions where my stepper motor said aux 5,6 on ecu. I was wondering do I configure the IAC as a Solenoid or a stepper motor on PC link? I attached picture of IAC. Thanks

    If I use some thing like this? Use 87 to ECU pin 65, 86 to fan switch?

    Fault codes Errors

    Thanks Adam. That worked. I got another question. My fan setup on my car doesnt seem to work so I was thinking could I wire out my fan switch that is in my rad to my Ac clutch output and change it to fan on software? The switch is a thermo switch and it has a relay. Could i just wire it straight to ECU to AC clutch relay output and do I have to use a relay? I attached a pic of my fan switch. It is 2 wire ground and 12v

    G4+ VR4link

    Hello. I just purchased link VR4 ecu, link ethanol content sensor and XS loom. Can I wire the ECS to the XS loom? Do I connect all three wires to xs loom or just the input and connect ground and power to ecu? Sorry I am a noob.
