Hey Ron, since your 2023 Toyota Tundra doesn't have the tow package currently you would need the 4-way kit part # C85FV for the taillight functions of the trailer wiring. Then if you needed to convert to a 7-way you'd also need the part # 37185. Does the trailer have brakes?

The truck does have wiring currently just not the hitch receiver. The wiring is just plugged up to dummy plug
