The res valve is in the center of intake and between the throttle body and valve cover.

You might have some sort of chamber bolted under the black plastic intake ( towards the rear ) I think this is for noise. My 97 SL320 does not have it but my 97 E320 parts car does. Both have a M104, I don't have any info as to where the box is attached to as the E is still assembled.

It's vacuum comes directly from the intake manifold though there is a short legnth of hose that can dislodge if the valve is disassembled. The large piece you see is the vent for the valve when its powered down .
