Could somebody identify this wire for me?
 

It goes into some thing on the exten manifold but the plug is broke, and i want to know if its important or not. Its the little white plug in the middle http://webpages.charter.net/vtecpreludez/identify.jpg

If it's got 2 pins, it's probably the intake air temp sensor plug...The Bypass air valve plug should be somewhere near it in the small stretch of harness too, it's a little bigger...On an S4, anyway...
