Can someone tell me what the white connector on top of my 22RE is used for. It its just sitting there waiting for a hook up of what I do not know.

 

AC idle up VSV.

Can't find a photo that's not on Photobucket and they suck so...

Notice the plug in your intake, that's where the power steering and AC idle bypass valve lives, you dont have one and likely don't have AC either.. subtext don't worry about the loose plug
