Battery Isolater

I recently had the OEM Tow Package installed on my Ridgeline. I was looking at a camper and they mentioned the need for a seven prog connector which I believe came with the tow package and they also mentioned the need for a battery isolator to prevent the trailer from discharging the tow vehicles battery. It went on to say if your is equipped with a 7-prong adapter it may or maynot be wired for charging. Does anyone know it the oem wiring and tow package came with a battery isolater. This is my first look at towing something and so I am ignorant about some of these terms. Any light shed would be appreciated.
thanks

You don't need a battery isolator. Unlike some other vehicles, the charging wire from the RL to the trailer is dead when the ignition is off.

Attached below you will find a link to the install instructions for the trailer hitch wiring harness. At the end of the directions, you will find the wiring schematics for the OEM harness.

Thanks for the info on the battery isolater.
Now on a somewhat related matter I am wondering about this statement:
"The harness includes a pigtail connector to snap into an electric trailer brake system and even allows you to charge a trailer battery when using the 7-pin connector."
What is a " pig tail connector" and should I have one? I think it aslo called a trailer brake subharness. After the dealer installed my Hitch and Harness kit I received the hitch pin, hitch pin clip, ball mount, and recieiver cover, but no trailer brake subharness, or any other connector. I'm thinking the subharness may be installed somwhere in the hitch system, but not sure. Is my trailer brake MIA? thanks again for helping me with my learning curve here.

drc8404,

If you look at the bottom of page 10 of the install instructions in post #3 below, you will see a picture of the "pig tail." It is the sub harness for attaching a brake controller. Your dealer should have given it to you after they installed the hitch. They may have put it in the glove box or somewhere in the truck. If not, you should ask them for it as it comes with the hitch wiring harness.

The pig tail allows you to connect a brake controller to the truck without having to cut/splice into any of the trucks wiring. It attach's under the dash by the emergency brake. You only need this if you are going to install a brake controller.

Here is a link to a thread that explains how to install a brake controller with pictures of where the pigtail connects. Some brake controllers have an adapter that works with the RL and do not require use of the pigtail.

Thanks, I contacted the dealer who installed the hitch and harness and they are going to order me a trailer break harness on them..

Does the 7 pin connector also come with its own "pig tail"? I am assuming there is some sort of connector that goes from the trailer/camper into the 7 pin connector on the hitch. Thanks again for you help. I am trying to get this ready for a camper I am in the process of ordering and will need to tow.
I want to be ready when I go to pick it up with everything I'll need.

DRC8404,

The trailer will come with a connector that plugs directly into the truck. Since the OEM wiring harness has both a 4-pin connector and 7-pin connector, you should never need a pig tail. Just plug the trailer in and you should be good to go (unless the trailer has brakes, then you need the brake controller installed).

Thanks, the issue is beginning to become clearer to me now..
