Could use some help identifying this part

Under the intake manifold in the front towards the drivers side and directly behind the power-steering pump reservoir ... there is a part that has one electrical plug (facing towards the drivers side) and two hose attachments. One of the hoses goes towards the drivers side and attaches near the drivers side fender.

It's the other hose attachment points towards the passenger side - I need to know where this hose attaches to on the other end.

Any help would be appreciated! This is on a 2000 323i.

I'd suggest this thread from the E39 bestlinks (the E39 M54 being the same, essentially, as the E46 M54):
- Getting to know your M54 engine, an in situ photo & identification guide to every visible part in the engine bay (1)

See post #78:

Here is a picture of the Manifold where the TB attaches, but I don't see an opening for any hoses in the area.

There are two hoses that come out of the intake manifold directly behind the TB. One is the Brake Booster Hose and the other hose I thought was only to let out excess vapors and did not connect anywhere.

Is it possible that the second hose actually connects to this part? And if I left it unhooked, how bad will the car run?

The hose coming out the "back" of this device (the opposite end from the electrical socket) goes to the spigot under the middle of the TB, right next to the hose that comes from the brake booster. The other (side) spigot has a hard plastic "hose" thay goes to ? May be able to help further in the light tomorrow.
