location fuses for trailer tow package and of wiring for trailer brake controller
I have a 2013 holiday rambler 40 DFT. When I first started towing my car, I hooked up a temporary wire from the 12 v pos lead in the 7 pin connector to keep the car battery charged. The mistake I made was to leave the key on in the car overnight and some lights and it discharged the battery in the car. The next morning when I started the motorhome it sent a large surge to the car battery which blew a fuse. I have not been able to find the location of the fuse in the manual. When I had a car braking system installed , the installer used the trailer braking wire in the 7 pin connector as a battery charging wire. He cut the wire and taped up the end that goes forward and connected a 20 amp fuse to the engine batteries to the end that goes to the 7 pin connector. This has worked fine for towing the car but if I want to tow a trailer, I cannot use the trailer brakes. If I can find the location of the fuse for the 12 v connection and also the location where to install the trailer brake controller, I could do both. Any help would be appreciated.
