He couldn't find it either.
Turns out that if the dealer installs the tow package, they don't get the wired in socket for the brake controller pigtail. You get the works that looks as if it is factory, but you have to hard wire the controller in. We found the BLUE brake wire coiled up and strapped to the relay box and the 12 volt power to the 7 pin up in the passenger side of the engine compartment. The tech warned me that the electronics on the 2011 are VERY easily damaged if you short out while looking for the wires to tap into. I could do it, but you know, I think it will be worth a few bucks to let them do it. I just want to tow with this big 5.7L Hemi! AT least I got my $20 back on that useless pigtail. Good luck if you are in a similar situation.
I guess it begs the question, "if you knew you needed to tow something large enough to need a brake controller why didn't you get the factory installed tow package"? Virtually every one of the WK2's I saw on the lot had the factory package regardless of engine or model. I'm just sayin'

Re: Electric Tow Brake Controller

Here is a new wiring harness that will fit a couple of different brake controlers. This one will fit the 2011 Grand Cherokee and the 2011 Durango. This is a preorder.

Re: Electric Tow Brake Controller

This site saved me time and money. I bought my Overland with the hemi to tow my race car. My Jeep did not come with the harness in the glove box so after reading this thread I called my salesman and he said come on over and get it. Thanks for the help, I will be installing the controller tomorrow.

Re: Electric Tow Brake Controller

The job was real easy. I unclipped the factory connector to make it easier to work on. I also wired connector's on my controller and the other end of the harness that should of came in the glove compartment. Dealer gave it to me free so no harm. Tucked up all the wires and re clipped the factory connector and bobs your uncle. Wish all jobs were that easy. Too bad the instructions couldn't of had the correct colors though. Thanks again, Jim.

Re: Electric Tow Brake Controller

Hi, I am curious to know if anyone without the factory tow package BUT had the factory wiring under the bumper got it to work (with or without a brake controller). I cannot get the stop/turn to work, only the tail lights. All tow fuses check good. Thx

Re: Electric Tow Brake Controller

Hello,

I know this is an old thread, but I need some help.... I have a 2012 Grand Cherokee that did NOT come with the factory tow package. I have since bought and installed a factory hitch and factory wiring harness, FAR less than the dealership would do it for. I took it to the dealership and had the tow option turned on. All I have under my dash is the blue control wire (which I put there) I have a Mopar brake controller with the female pig tail. I do not have the male connector that comes with the pre-installed tow package. I called the dealership and asked for help and all they could tell me is that the plug is there due to my jeep having a tow package, they couldn't understand that they were the ones who turned it on. spoke with the director of service from corporate, he sent me a pig tail that is supposed to plug into the (non) existing connector. All I need is some knowledge on where to find the male 4 pin to connect the controller I have. if not does anyone need a mopar controller for 115.00?????
thank you all for the help

Re: Electric Tow Brake Controller

If you do have it, it's very close to the hood release.
You to pull down the covering to access it. A few inches towards fire wall and few inches up from the lowest edge of the dashboard.

Re: Electric Tow Brake Controller

I do not have it in my vehicle, I installed the wiring harness that runs from the fuse block to the trailer hitch. The factory trailer wiring harness did not come with the male connector for under the dash that is usually by the obd II/hood release

Since your GC did not come equipped with the factory tow package, it is not prewired with the brake controller connector under the dash. Therefore, the pigtail with the connectors sent to you by the "director of service" is of no value. You'll have to hardwire the controller using only the bare-wire pigtail that came with it.

This isn't that hard and there are a number of resources online that can provide guidance. (etrailer.com is one) Some expertise will be required to locate the correct connection point for the brake light circuit, and one of the factory chassis ground lugs (the preferred point) under the dash near the controller mounting location.

Beyond this, it will be adding a typical 30 amp circuit with an auto-reset circuit breaker connected as close as possible off the battery + terminal. The last connection will be the blue wire you've already run.

You've come this far, don't give up now. If you're not comfortable tackling the wiring, trailer hitch installer do these every day. While competent, no professional installer will be as thorough as you could be however.

Re: Electric Tow Brake Controller

I appreciate it. That was what I decided last night, was to hard wire it in. Call me crazy, but I was trying to keep it as close to OEM as possible. Thank you for the reply

This was changed over time and only holds true for earlier model years, to the best of my knowledge.

I understand. So, take a look at this harness and the installation instructions:

Mopar Electric Trailer Brake Controller - Item # 82210512AC #82210512AC

This is as close as you'll come to keeping it oem. I don't care for it because it taps power from the accessory outlet on the center stack. Not sure, but this is likely a 20 amp fused supply which could limit your braking to a single axle. If the fuse should ever blow, you'll loose trailer braking. Auto-reset breaker protection is much preferred.

The instructions do locate the correct brake light switch connection to make though.
