Anyone with Fast Xfi..... quick question
 

Im looking to see what color wires and what order they go into the IAC sensor. Mine were extended a long time ago.. and i have 3 reds going into the connector and 1 black. I want to make sure i dont have any backwards or something. I havent used the IAC because it never worked right...

I traced the wiring and found good connections to the colored wires... but cant find a diagram to make sure they are correct.

Should be red, blue, yellow, and black.

I upgraded to the 2.0.. and its been a nightmare trying to recalibrate all the new settings...... uuugggghhhh.

thanks.

late model IAC is

A red
B blue
C yellow
D black

I got that... but what pin is a, b, c, and d supposed to be?

thanks.

that is what they're supposed to be. Maybe I don't understand your question. The A pin on the IAC should have the red wire from the ecu. The B pin should have the blue wire and so on. These wires come from the gray 25 pin harness, which also has the fuel pump, fan, and power adder harnesses.

Ok... maybe i didn't see the letters on the connector. I'll take another peak...
thanks!!

the letters will be on the connector and the IAC. Get your glasses or magnifying glass, they're small.......... :lol:

Your right!!
Thanks!!

you're welcome.

Dang... It's all wired right. I was hoping it was wrong and it would solve the issue!! O well.

Thanks again!!

what is the problem?
