Early E36 M42 throttle body-- where does this hose go?

[jaredmac11]

Let me know if the image doesnt work, trying to be lazy here.

This hose was disconnected when I collected the engine. I assume this is going to a charcoal canister but Im wondering if it was the DISA? Its been 12 months and I lost a few pictures so Im lost here.

If its not going to the DISA, where does it go?

Purge valve.

Yep looks like it goes down to that air tank, AGR device. Which goes back up to the disa.

Purge valve.

and then the carbon canister.

DISA gets its vacuum from a small tube under the intake.
