Battery charger?

So I would like to charge my pop up trailer while driving via my 2011 Compass but all I have is a 4 pin wire harness. So how do I do it? And Go.......

Well you could do it two ways. Run power and ground to the back and use an Anderson plug or wire up a 7 or 6 way plug and do the same on the trailer

So if I run a Anderson plug to the back of the jeep and and wire the other end up to the battery would that cause any problems with my jeep battery. I also would install a 30 amp fuse near the jeep battery.

Won't hurt a thing. definitely use a fuse with it for safety. Use their 50amp ones. Their small and pretty cheap. Get a set and some battery cable, if you can't get any cable. Buy some jumper cables and cut off the clamps and BAM! instant battery cable.

It should not - I've done similar setups in the past. You may use an Anderson SB50 with 8AWG or 6AWG wire for safety, a "local ground" at the plug (so you only have to run one lead,) and fuse for about half of the alternator's max output rating (it's possible you can run more than 30A to the trailer!)

I would be highly inclined to run either an isolator or a solenoid to control power to the SB50 to the trailer, unless you're sure you will remember to always disconnect the trailer when you've shut down the engine.

(A 7-way will only be good for something like 20A. Andersons can typically be "surged" for twice their rating, will sustain a higher max rating anyhow, and are easier to install than wiring up a 7-way barrel plug.)
