m52 swap charcoal canister/ fuse box vac.
 

I pulled the obd2 met drop out, out of a 1997 328i. All of the swap went super smooth except for a few things. First being a vac hose from what I believe to be the charcoal canister. On the 328 it went to the fuse box, in my obd2 ti, this vac port does not exist on the fuse box of the ti, where should it go?

Also it keeps throwing codes of o2 heater that didn't exist before the swap.
Also has a maf code that didn't exist before the swap.

Any help is much appreciated
