Expert Reply:

We have everything you need to get a brake controller installed on your 2019 Jeep Wrangler Unlimited. If you don't already have a brake controller I recommend checking out the Redarc Tow-Pro Elite # RED44FR because it takes up little to no room in your dash area and it has both proportional and user-control braking options which give you the best performance whether you're towing on the highway or going off-road. The parts you'll need to get this installed depend on if you have the factory tow package or not:

Factory Tow Package
Tekonsha Plug-In Adapter - # 3073-P
Tekonsha to Redarc Adapter - # 331-TPH-017

Without Factory Tow Package
Tekonsha T-One 4-Way Wiring - # 118786
Universal Wiring Kit - # ETBC7
Universal Stop Light Switch Kit - # RM-751000

For the factory tow package everything is plug and play. There will be a connector under the driver's side dash you'll connect the plug-in wiring to and then the Tekonsha to Redarc adapter keeps you from having to do any splicing at all.

Without the factory tow package you'll need to run some wiring. The T-One tees in behind your taillights and is powered by the black wire you run up to the positive terminal on your battery. From there you'll use the ETBC7 kit which plugs into the T-One 4-Way and then gives you all of the other wiring and parts you need so you can hardwire in the Redarc.
