X3 INTERCOOLER FAN OVERRIDE PLUG & PLAY SWITCH AND HARNESS KIT
This is a fail proof, plug & play kit for the X3's that give YOU full control of your Intercooler fan. The factory fan for the 120hp models will not turn on at all, the 154+hp models ONLY turn on under 80% load. This kit allows the IAT's to be lowered by maintaining cool air passing the through the intercooler even at cruising speeds. Cooler IAT's = MORE POWER!?ß
*Required component for 120HP X3's doing a intercooler upgrade.?ß The factory ECU will not turn on the fan!
*For already intercooled models this is an over ride that allows you to run your intercooler any time at the flip of a switch. Your factory intercooler settings will still activate the fan, however this allows you to turn it on even sooner!?ß

Yes can I get a wiring diagram of this harness I'm trying to use this harness to turn my x3 fans on using a temperature switch instead of a rocker switch and am having a little trouble getting it to work right
Hey Shawn, email us.
I think you’re doing this the hard way.
That control logic is already in the ecm.
We can set the radiator as well as inter cooler fans to come on based off, tps, speed, and temp.
