You can connect a new 12 volt line directly to the 12 volt batteries in your camper. To provide power to a winch it must be wired to a vehicle battery or a separate auxiliary battery designated for use with the winch.
Battery Isolator
Rv auxiliary battery wiring. Run two wires from the trailer end of the seven pin connector to the trailer battery. Therefore it is recommended to use good quality plugs and cables so that the transfer rate efficiency is maximum. The rv batteries charged with solar panels or additional batteries must allow for minimum loss of power while transferring. The negative terminal of one battery is connected to the positive terminal of the other battery. The trailer positive lead should be connected with the first batterys positive terminal. All rvs run off of the 12v system.
For example a solar panel charging system is often directly connected to the battery for efficient charging. Use two different colors of wire such as red and black so you can easily identify positive and negative. This is especially useful for circuits that will draw heavy loads or provide charging. An rv battery is a collection of lead acid cells. Another set of cables connects the remaining positive and negative terminal to whatever you are connecting the batteries to. There are several ways to wire your winch depending on whether your winch is mounted on a vehicle or a trailer the type of winching and the frequency of winching.
Electric winches require power from a battery source to operate. Which is why they are called batteries in the first place. To make a 12 volt battery which when fully charge will produce approximately 126 volts. The 100 position of your 7 way carries this circuit. You can put a maintenance charge on your trailer battery with the 12 volt accessory circuit of the 7 way. Most common batteries that are used are 6v batteries in series or 12v batteries connected in parallel for more amp hours.
The negative lead of the trailer is connected to the the negative lead of the first battery. Connected batteries should have the same voltage and amp rating. You can even combine the different systems like two 6v batteries in series connected parallel to a 12v battery. Then connect the two positive posts together with charger wire secure the clamps and then do the same with the negative posts. You can use standard 10 gauge electrical wire but thicker wire will carry more current and give a better charge. It takes 6 cells connected in series.
You would just need to run a length of 10 gauge wire like part 10 1 1 sold by the foot from this pin to the positive terminal of the battery. A jumper wire is used to connect rv batteries. Each cell when fully charged will produce close to 25 volts.
