When bringing home our 2011 Heartland Bighorn 3185RL we blew a tire that ripped all the electrical from the rear left side (driver side) of the trailer. We now have no 12v power in that pullout, nor does the refrigerator work. We have a maze of wires dangling that was ripped out of the black flexible wire housing. Our main concern is to get the refrigerator operational. We are not concerned about the telephone, satellite, tv cables at this time. Anyone have a wiring diagram for the rear pullout and more specifically how the refrigerator is connected in that wire channel that is affixed under the rear pullout.
