Hey Mark, thanks for reaching out!

It sounds like you're looking for the T-One Vehicle Wiring Harness # 118266 which has 2 connections at the back of a 2017 Frontier and a harness that connects under the dash.

I'm attaching 2 photos of these connection points as well as an installation video for you to verify this is what you're talking about.

Were you wanting a brake controller as well, or just looking for the parts for adding a 7-Way at this time?

Hey Mark, how did things go with the T-One wiring harness for your Frontier? Did the connections at the back and under the dash match what you had on your truck? Your update could make it easier for the next person working on the same setup.
