A connection system (10) for communicating multiple signals between a steering wheel (16) and a steering column (22) of a vehicle over a single wire (24) is provided that uses time division to multiplex multiple signals. A plurality of signals are multiplexed together ranging from two to as many signals as desired. Input switches (32, 34) are grouped together to form a ladder multiplexer, such as a resistive multiplexer (28, 30), that includes voltage and current muxing. A plurality of ladder multiplexers are joined together in a time division multiplexing scheme that operates continuously. An analog line may be added as a single channel. A marker pulse is used to signal the start of each time window to be divided for all the channels. Time division multiplexing is provided by a number of switching means.
