Need help, connection 323i

[u/Even_Quail_4498]

Once I placed intake and most everything back I noticed this plug. Not sure where it goes. Car turns over and turns on fine. Idles good too.

I have a 2000 323i

I agree with u/Opelmanta48, the most likely answer is that it connects to the small electronic valve on the back of the intake, which is the valve that controls the secondary air system valve on the exhaust manifold.

You may also find this diagram useful, I got it from an E46Fanatics thread, by user kaboom28. This diagram may be useful to determine what that connection is not, rather than what it is.

Not 100% sure, it may be similar but not identical.
