on the tongue is an electrical box and then next to that there are 2 small connectors covered by a rubber cover that look like junction connectors, my guess is one for each slide out, one was sparking and getting very hot, and one of my slideouts quit working, here is a pic, i pulled one of the connectors off the trailer frame to keep it from arcing, what are these called and are they available at any rv supply?
each connector has 2 threaded prong hook up
