Does this harness allow you to charge the trailer battery, does it have a supply to the trailer?

Yes it does, also to connect electric trailer brakes. It will work in place of or along side of the 4 pin connector. I have both installed on my jeep. It was an easy install.

None. It plugs into your cigarette lighter socket. How you handle the light connection on the tow vehicle for break and turns is up to you.

I wired mine directly to the battery that is mounted to the trailer tongue. Probably could wire it to the 7-pin, but then the tow vehicle would always need to be hooked up to use the jack.

You can tie it directly to the battery. If you are handy you can make a detachable plug as well to make it convenient. It comes with open leads.

No.It connects to the battery harness with the quick connect that you need to get.This is an excellence addition for usb power.

yes it does. We bought for our toy hauler trailer. Was concerned it would drain the batteries quickly, but it works great. We watch a couple hours of dvd movies and hardly uses up any battery. The tv sound quality is not very good though, we run the sound through our trailer fm radio

No, only the vehicle connector. You will have to purchase the trailer connector separately if you don't have one.

It does charge the battery. They are 2x louder than a Honda or Yamaha. You can't beat it for the price though. We are camping at Redfish Lake Idaho with ours right now. We just keep it on 2 long cords and get it as far from camp as possible.

Yes. I have my controller mounted in my pop up hard wired to the battery. On the supply side (panels) I made a harness thst combines three ends into one and that is in my shore power port on the side of the trailer. So when I set up, I just place the panels on the roof and pull the harness out of the shore power recepticle and plug 'em in. Just got back from Bodega Bay, CA yesterday and the system works great!

Yes. It is a little plug in that goes into the battery leads under the seat.

No, it only has small alligator style clips. It is for charging sealed lead batteries that are used in deer feeders, certain large flashlights, etc.

Yes it does. You can buy longer leads if needed too. The included ones reached from the battery to the grill. This makes it great for moving the car around the garage without having to take off the cover. Just to let you know the charger works great on newer / fresh batteries. I have had a problem charging a 5 year old battery that probably should be replaced. After cycling through, the charger says it can not be charged.

It does not. I has a harness with a red and black wire (hot and ground) to be wired into a 12v power supply.

It has the plug in harness. It kinda short though, make sure mount the control close to the plug in. My Silverado plugs to the left of the brake pedal

Yes. Whether buying the complete unit or the power supply insert and installing the insert, the completed unit has the capability to both charge the RV battery automatically and provide 12 volt power to RV accessories. I assume the original power supply was set up by the RV manufacturer to do both.
