El Jefe - that is the exact pump I bought
You'll be good as long as no one has already changed the pump and modified the bracket/connector before you got there. Even though they call it an "Aux Water Pump", it's for the inter-cooler on our cars.

EDIT: Also if you decide to go with the 002 pump - the inlet and outlet ports are different lengths (longer) than what is on the OEM pump, so you will have to modify the hoses if you go with that one. Additionally, the Mercedes guys are saying this pump (the 002) is also crap and I think it was the original pump for the 02/03 SLK 32s.
