An electrical system 2 for a motor vehicle comprising: an Electronic Control Unit (ECU) (8a, fig3), the ECU configured to control the operation of one or more systems on the vehicle; a multiplexed data bus 102 communicatively coupled to the ECU to carry multiplexed control signals to and from the ECU; and a motor vehicle relay control box assembly 100. The motor vehicle relay control box assembly comprises: one or more relays 106a-c; and a controller 104, communicatively coupled to the multiplexed data bus. The controller is configured to: decode the multiplexed control signals from the ECU to generate one or more decoded control signals; and control the operation of the one or more relays according to the decoded control signal. The controller and relays may be in a common housing 108a, or the controller may be in a further housing (fig.2b). Expansion slots 108c may be provided to increase the quantity of relays of the system. Controller may comprise a relay driver module 104c, processor module 104b and/or decoder module 104a. A method of retrofitting a motor vehicle relay control box assembly and a method of upgrading a motor vehicle relay control box assembly are also provided.
