Hey Dan! Does your factory connector look like the 7- and 4-Pole Trailer Connector Socket # HM40975? This is the same as the # N40975 you looked at but without the relays. This is designed to fit a standard USCAR connector like the one in the attached picture. If you have a different style let me know, or go ahead and email me a picture, and I can help you find the right one for your 2023 Frontier.

Hey Dan, did the 7- and 4-pole trailer connector socket end up matching the plug on your Frontier? Knowing what you found could help others trying to replace their factory connector too.
