Another link for 722.6 electrical plug
 

Just found this link. It offers some great pictures on replacement of the plug. One should be aware that new data plugs (MB calls it a pilot bushing) now come complete with BLACK o-rings (white ones have been superceded) and are available from the dealer or online for around $7.00. P/N is 203-540-02-53.

Thanks for the link. My old one had red o-rings and the replacement has black o-rings.
