Abstract
Abstract The invention comprises an electrical-fluidic control system adapted to control essentially every function of a vehicle. In a preferred embodiment, the invention comprises a single harness formed of electrical and fluidic transmission paths, respectively connected to sources of electrical and fluid power, control means for applying coded control signals to an electrical signal transmission path, and receiving means connected to the electrical signal and power transmission paths for receiving said coded electrical signals to selectively activate electrical and fluidic switching means to operate desired load devices for performing selected vehicle functions.
