Hey everyone, As part of my rebuild, I've replaced the 6pin square connector with a 7 pin round connector. I'm utilizing the 12V AUX wiring from the TV to the pup. I'm going to add a deep cycle battery to the PUP and connect that to the 12V system as well. Currently the only 12V devices in the PUP are the lights and the refrigerator. But the refrigerator will run on 120V AC most of the time since we mostly camp at places with hookups. So I have the 12V and Ground wires coming from the 7 pin connector into the area under the bench seat that has the converter. I figure I will put a battery in here as well since there is space (need an AGC battery for this, right?). I have the 12V & Ground wires from the refrigerator coming in here, and I also have the 12V & Ground wires from the lights (ceiling lights and also porch light). My question is, whats the best way to physically connect all these? I'm not sure what it's called, but I was thinking to get two of those metals bars with the screws in them. Connect all the grounds to one bar and all the 12Vs to the other bar. Is this a good plan? What would be better? I will also put a circuit breaker between the TV and the wiring inside. Is that correct? What amperage breaker do you guys suggest? 20A? 30A? Do I need fuses in between the converter/battery and the lights and between the converter/battery and the fridge as well? This is the kind of bar I'm thinking about. If I go this route, where's the best place to get these? Radio Shack or somewhere else locally? Somewhere online? Thanks everyone! I love this site!
