CONTROL SYSTEM FOR A TOWED VEHICLE

There is disclosed a communication system for delivering power and control signals to control the activation of electrical components in a vehicle comprising: a power source for generating a power signal to supply power to the electrical components; a computer controller for generating control signals to control operation of the electrical components; a slave unit operatively connected to both the power source and the computer controller to receive the control signals and to convert the control signals into data signals for transmission to the electrical components; a power supply line for carrying the power signal, or the power signal and the data signals, from the slave unit to each electrical component; and a master unit located remote from said slave unit and configured to receive the data signals from the slave unit and to verify the data signals for further delivery to the required electrical component.
