Shape of 602 Block Heater Element Connector
 

From what I understand, all 60x engines came with the block heater element installed; but many, of course, came without the cord installed.

So I bought a cord from Carquest....it's the one available through Worldpac. It has a rectangular connector, about 5/8" by 1/4". But in some pics I've seen of blocker heater elements, at least on a 603, it looks like there's a circular connection.

Has anyone wired up a 602 from a 1990-3 300D? If so, what kind of connector did you find?

Thanks.

Block Heater Plug
 

From an OM602.962 2007 Mercedes Factory Reman of a 1992.

Excellent....that's exactly what mine looks like.

Got under the car today....my block element has a circular connector. However, the rectangular plug seems to be a snug fit. So I may just use that one or spring for the circular plug with the threaded connector.
