Hey Al. To add a 4-way and 7-way connector to your 2018 Dodge Durango you'll need two separate parts since you do not have the factory tow package. I have listed the ones you'll need below:
4-Way Connector - Curt T-Connector Vehicle Wiring Harness item # C56336 - This custom-fit T-connector plugs into your Durango's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. It will provide you with a 4-flat connector.
7-Way Connector - The second harness you will need is the Universal Installation Kit for Trailer Brake Controller item # ETBC7. The kit includes a pre-wired 7- and 4-way trailer connector that mounts easily at the rear of your Durango with an included bracket. This kit is designed for use on a vehicle with an existing 4-way flat trailer connector and plugs directly into it.
You will then connect the blue wire to the blue wire on the brake controller, connect the black wire to the positive post on the vehicle's battery, the white wire to ground, and the yellow wire to vehicle's reverse circuit if applicable. This will provide you with the ability to control your trailer's brakes and also provide you with a 12v power wire for you trailer's accessory lights.
What kind of trailer are you pulling? Do you also need a brake controller? You can add this information and any other questions you have in the box below that says Reply to Jerred H.

Hey Al, did the Curt T-Connector and the Universal Installation Kit work out for your Durango? I'm curious to know if everything fit well and if you were able to get your trailer set up, as your experience could help others with similar needs.
