Expert Reply:

The trailer wiring circuit associated with the functions you mentioned like battery charging or lights is the 12 volt accessory circuit. If you are using a 7-way connector like I believe you are that is the circuit in the 1:00 position as you face the opening of the connector. To activate this circuit you need to run a length of 10 gauge wire like part # 10-1-1 (sold by foot) to the positive post of your Tacoma battery through a breaker like the # 9510.
