In order to power the lights and brakes on your horse trailer you will need to add a 7-way to your 2018 Dodge Durango. The first thing I would do is see if you have the factory tow package connector behind the rear bumper. I have attached an installation video below for the Hopkins 7- and 4-Pole Trailer Connector Socket # HM40975. If you start watching at the 2 minute mark you will see the connector I'm referring to. If you have this connector then you will be able to use the # HM40975 and that is all that will be required.

If you do not have the factory tow package connector you will have to start by adding a 4-way with the Tekonsha T-One Vehicle Wiring Harness # 118617. This plugs into the connection points behind your tail lights. Once that is complete, you need to install the Universal Installation Kit for Trailer Brake Controller # ETBC7. This kit comes with the adapter, breakers, wiring, and everything else needed to upgrade your 4-way to a 7-way.

For a brake controller I recommend the Redarc Tow-Pro Liberty # RED24FR. The main unit of this brake controller mounts behind the dash with only the control knob visible in the cab. This keeps it out of the way and also gives it a nice clean OEM look in your vehicle. If you have the tow package there will be a connector under the dash which will allow you to use the custom fit wiring harness # RED77FR for installation. If you don't have the tow package and install the # ETBC7 for your 7-way then you will need the # RED69FR for installation.
