Hi all

I was dropping my 2006 Diplomet 40 pdq 400 hp coach off for winter storage after cleaning and pressure washing the undercarriage of grime and dirt. Just As i was closing the door on the storage unit I notced this electrical connector hanging down just behind the mud flap on the drivers side. It is a three conductor flat cable that has a orange what appears to be some kind of heat or chafing protector around the black flat 3 condutor cable. The end has a threaded connection and what appear should be 3 female pins. Mine appears to have broken off and has one of the pins from whatever it was conected to still in the connector. It does not appear that the threaded collar was attached as it does not have the coresponding broken peice in it. I am attaching 2 photos

We have totally different coaches, but that is exactly like the plug that goes to my water heater's electric heater rod. Exactly.

THIS maybe the engine side of the block heater. Look for the other end of the connector.

I beleive JB nailed it! I googled engine block heater for cummins and found the replacement cable to be exactly like the one that is dangling. Then I looked at the cummins block heater picture and sure enough its threaded. I guess somewhere along the line it was left looose or not reconnected.

Thanks to all esp JB!
