Hello my name is ***** ***** thank you for your question.

So if your 2017 Titan did not come with a tow hitch, they did not have some fuses or relays installed for the wiring for the tow to work. So when you have a hitch installed, they sell a sub harness to attach to the harness of the truck so the Tail lights, directionals, brake lights and so on work when the trailer is connected. So you would need to install a Trailer Tow Relay and maybe a few fuses in the fuse box under the hood.
