Hey Kel, best solution to have both a 7-way and a 4-way on your 2021 Ford Bronco with non-LED lights would be to start with the 4-way part # TK33VR and then use the 7-way adapter part # 37185 which has a 4-way connector on it as well. There isn't a 7-way kit for your vehicle configuration due to the lights you have. Does your trailer have brakes?
