I have a 2012 GC Overland with the HD Trailer Tow Pkg IV.

I am getting a brake controller for the new travel trailer I bought.

Does installing this automatically activate the charging circuit which is one of the lines running to the 7 prong plug on the bumper? Or do I also need to run a line for that somewhere/somehow?

Basically I want to know that if I installed the brake controller myself will I then have the charge circuit wiring to charge the trailer batteries while I am running? Or do I also need to have someone run this wiring? (In which case I might as well have a trailer jockey do the entire install for me?

Thank you.

I actally don't know this one off the top of my head. I will ask tomorrow if someone else doesn't answer first. The plug in should be under the dash and you can purchase a direct adapter to Prodigy Controllers etc but not sure if the charge line is already connected.

Willx,
That would be really appreciated. I finally figured out what I needed to order in-so-far-as the Controller and Connector Pigtail. But before I place the order I needed to know if the charge line will work or not. No sense in my doing all this work if I'm going to end up needing an installer to run the charge-line. Whatever you can share would be great. And thank you.

You want the adapter cable either way. Which Brake Controller are you using?

Spoke to one of the techs. It should be live from the factory but it is super easy to liven up if not. He said he has seen some off but it is a 30 second fix.

IMHO, if you are looking act towing something over 1500 pounds consider the Prodigy P2 or P3. With heavier trailers they give the most natural feel.

Running a P3 in my Durango and Braking is so smooth and much better release than the Reese I returned after a single trip.

I just did a charging setup on my trailer, the power is already on, and connected to a 30amp fuse seperate from teh other towing fuses. I ened up running new power and ground wires with a AUX relay. The wires used for charging are 14-16gage from the factory, really small and i found the ground on the trailer getting warm. not to mention your not gettting much of a charge with that size wire at that lenght. I was able to find a replacment 7/4 way that fit in the same spot from e-trailer and wired 6 or 8gage hot and ground with a 30amp fuse on the truck side and trailer side it works great
