Part info Help

Replaced the plenum boot on my 84 500SEL and replaced a part called the fuel injection control valve, MB# 003-997-00-36. The part is attached to the throttle body and is activated by the throttle linkage which activates a small plunger. There are three vaccum ports on the valve.

Can any body tell me the correct vaccum routing and what systems do the operate.

Many thanks,

Rustys380SL, can you be more specific. And do you have vacuum diagram that would clarify? Doesn't the canister in the fender, I don't know what its called, is somehow connected to this system. Any help will be appreciated.
