Hey Kalani, thanks for reaching out!
You can actually use an adapter plug like the Hopkins Endurance # HM75MV to get both 4-Way and 7-Way receptacles on your 2015 Toyota Tacoma.
To install this you'll pull the USCAR connector plug from the back of your current 7-Way, secure the Hopkins adapter to your truck, and then plug the USCAR connector into the back of the Hopkins adapter and you'll be good to go!
Are you just needing more wiring options for towing a trailer?
