Oh my goodness, that Mercedes EPC has a steep learning curve! I spent about an hour fumbling around on the site while my 6 month old French Bull Dog was nibbling/yelping/jumping on me. I could not find the part. I think I found a relay on EBay, but the guy is really proud of them.

UGH..maybe I will call the dealer and/or email the guy on eBay.
