4 pin to 7 pin trailer plug

I need to reconfigure the 4 pin to a seven pin for electric brakes on my trailer. And is there a plug in for the brake controller? I did get the towing package,but it looks like all I got was the 4 pin connector for the lights. Any help will be appreciated , thanks

You will need to get the mopar 7 pin harness and a brake controller. You can go 7 to 4 pin but not 4 to 7 pin.

It's in the tech section somewhere. I just removed my harness from my 2010 today as I traded for a 12 and plan to use it for the new jeep. hardest part is getting under not lifted. And getting under the dash to the brake wire. but it works. Saw it for $94 from Jeep.
