I went to my dealership to get a brake controller installed and was told Jeep doesn't make one for a Series II.

How does Wagoneer expect us to pull a 7K lb trailer without a brake controller?

Did I just throw away $75K... any ideas?

In the same boat w/ my Series I. I just don't think that Jeep is offering the OEM controller. I'm pretty sure they will at some point.

However, I'm not willing to wait. There are several after market options available. I purchase one through eTrailer.com that even has a video of installation on a Wagoneer.

Here's the link to what I went with:


While I'm sure its cheaper than the OEM controller, it has to be installed on the dash and wont integrate with the vehicle's software. Bummer. But its the only option currently available and Ill be towing a travel trailer so I NEED a brake controller now.

I'm in the same situation as you. I have Trailer City in Hempstead NY installing a Reese brake controller with a plug n play adapter this Friday...

Kudos to Fiat/Chrysler for selling a truck that boasts towing a 7K+ trailer without hope of stopping safely with OEM parts!

You would have to get the Series II or III with the Heavy Duty Tow Package.

I just purchased mine yesterday and it has the integrated trailer brake and can haul 10k lbs.

What about for the series 3 do they make one for that series
Yes, Series III is available. Series II may or may not have the wiring behind the dash. There are codes relative to the builds that reveal whether or not. My truck was built before the wiring was installed behind the dash.
Series I & II, you're just out of luck until the MOPAR wiring adapter is made.
Caveat Emptor!

I've confirmed that I have the wiring behind my dash and I have a Series I. I've included pics. I will update tomorrow after I've installed my aftermarket brake controller that I linked to in my above post...

From what my research revealed, the OEM front piece is available. It's the adapter behind the dash that isn't.
I really can't say what's involved in the install other than it looks nominal (with the right tools) and plug n play

I don't believe the OEM brake controller is available yet outside of ordering the tow package. I've checked MOPAR's site and talked to a dealer's parts department.

In my Series I, the adapter for an aftermarket brake controller is installed. See my above post with pics included.

Below are pics with my aftermarket brake controller installed. The controller can be easily removed when not in use.

BOTTOM LINE - I now have working trailer brakes and can legally tow my Travel Trailer!!!

Curt makes a brake controller that works through your seven pin connector. I ordered one today for my Wagoneer Series II. Has anyone tried this option? Works through Bluetooth and an app on your phone. Looks slick if it does what it promises.

I can tell you the Reese Brake Controller + Tekonsha Adapter I had installed gave me nothing but 'check trailer light' and 'check trailer connection' error messages the entire trip I took this past weekend.

I don't need this shit. I regret buying the Wagoneer.

If you don't get the Heavy Duty Tow package you will run into all kinds of problems. You have to be very careful with their advertised Towing capacity vs the ACTUAL towing capacity of your vehicle. It is significantly reduced if you don't get the factory tow package (not just the hitch but the full package). With the factory tow package you get heavy duty engine cooling, the integrated break controller, a different rear differential and possibly a different suspension (not 100% sure about that). When you look at page 224 of the manual you will see all the towing ratings. Of the 14 different Wagoneer and Grand Wagoneer configurations only 4 can actually tow 10,000 lbs. Some can only tow as little as 7180lbs. I learned this the hard way with my Dodge Durango. I couldn't find one with the factory Tow package but the dealer told me "I can install the factory hitch...." Well that didn't give me the upgraded suspension and engine cooling which takes the Durango from 3500lbs towing to 6500lbs. If you really need to Tow over 6500lbs even with a Wagoneer ONLY get one with the factory Tow package. Which is currently really hard to find! I am still looking for one to replace my 2016 Durango.

What appears to be the problem now is the Jeep dealer needs to download software that allows the truck to accept the aftermarket brake controller, otherwise you are barreled with warnings to check trailer lights and trailer connection every time you hit the brakes.

My family and I just drove 600 miles enduring this cruel and unusual punishment akin to Chinese water torture.

The problem is, because the dealerships cannot order the brake controllers, they do not have the software. My dealership is asking Jeep for it for me.

Food for thought... when you're about to spend $75K on a Wagoneer that can't do what it claims, the Expedition or Sequoia can!!!

Bummer that you're having these issues. However, my aftermarket brake controller was pretty much plug & play and works great w/o any additional software from the dealer.

I believe that the software from the dealer allows the vehicle to accept the OEM brake controller and integrates the OEM controller with the vehicle's software - including additional pages on the dash & possibly the infotainment screen. After-market controllers will not integrate with the vehicle software even if the additional software is installed. I went through this on my previous vehicle - a 2018 RAM 1500.

Well, when I went back to the installer of my after non OEM Reese controller and Tenkonsheh adapter, they called Reese tech support to troubleshoot. They said the controller working was testament to to it being hooked up correctly and the truck needs to accept that.

When I went back to the dealer, they were who suggested downloading the software and said it has helped with other vehickls that experienced these problems, they just have to get the software for the Wagoneer by itself without waiting for it with to accompany the OEM brake controllers that are not yet available.

Why would I need to buy a Wagoneer with a heavy duty tow package that pulls 10,000 pounds when the Series II I just bought has a tow package than can pull up to 7,200 pounds and the toy hauler I am pulling is only 5,600 pounds?
