ABSTRACT:
In a method for driving electronic devices connected to a vehicle trailer tow connector a trailer electronic device control signal is receiving from a vehicle data communication network. In response to the received control signal, a solid state power control device is switched to connect electrical power to a selected pin of the trailer tow connector. The trailer electronic device control signal may be received from a wiring harness connector connected to a vehicle data communication network. A vehicle trailer tow connector module includes a module housing. A vehicle wiring connector and a trailer wiring connector are coupled to the module housing. A power control circuit is connected to a selected pin in the trailer wiring connector. A controller circuit is coupled to the vehicle wiring connector for receiving communication data from a vehicle data bus, and coupled by control lines to the power control circuit.
