If you don't have the factory 7-Way on your 2018 Nissan Titan XD then you will need the kit # N40975 which comes with a 7-Way/4-Way connector and the needed relays to activate the tow package. Aside from this we haven't heard yet about needing to add a relay.

What you might want to do before installing the Prodigy P3 # 90195 and Adapter # 3050-P is check your relays to make sure that they are installed. I tried looking up the locations in the online version of the owner's manual but it was very vague and didn't provide locations. If you check the fuse box under your hood it should have a list of which fuses/relays are for which functions. I did attach the installation video of the kit # N40975 on a 2017 Titan that you can reference for the relays. Since it is the same generation as your 2018 I would be surprised if the locations are different.
