Thanks sir! You're absolutely right. I connected the travel trailer and my brake model recognizes it just fine. Granted, I didn't tow it, will do next but it really appears my dealership does not know what they're talking about! Plus, they wanted to charge $100 for that software flash. Fingers crossed I don't get a surprise though when I head for my travels next week!

Do not wait till last min always do a test drive for something like that. Tow before to make sure everything is set up correctly.

Re: 2014 JGC Brake Controller DIY

Hi again!

I can confirm the Mopar trailer brake controller worked flawlessly in my 2014 Grand Cherokee. No ECU software flash necessary.

Unrelated, I did see elevated engine oil temperature pulling up hill on a long steep gradient. My temperature reached 260 F where normal is about 220 F. Analogue coolant gauge looked fine and the 260 F reading still was not in the hot zone. Was this a temperature to be concerned about?

Re: 2014 JGC Brake Controller DIY

The software flash is only required for folks who are adding towing aftermarket...if the vehicle came from the factory with the Tow Package, a 3rd party controller should be plug-n-play. (Literally plug-n-play if you get a pre-terminated cable, such as the one available from Tekonshia for the P3) The integrated Mopar controller "may" need additional computer work due to it's nature, but I haven't seen anyone post that actually bought one, especially since it's substandard compared to most 3rd party controllers from what folks are saying.

I did actually buy the Mopar brake controller and it does work without any software flash. I towed a travel trailer through the NC mountains and it worked just fine with pretty smooth braking after adjusting the agressiveness and progressiveness on the unit. How it would compare with a different brand I have no idea as this was my first time using one. Still, I don't think my hemi liked dragging the weight of the trailer over those hills. Engine oil temperature climbed to 260 F ! ~Tom
