MULTIPLEXING IS THE SENDING OF MULTIPLE SIGNALS OR DATA STREAMS OF INFORMATION OVER A TRANSMISSION LINE(S),
AND THEN RECOVERING BY SEPARATING THE MULTIPLE SIGNALS OR DATA.

EXAMPLE: INSTEAD OF THE ENGINE ECU (ELECTRONIC CONTROL UNIT) RECEIVING A DIRECT (HARDWIRED) SWITCHED INPUT
SIGNAL FROM THE CRUISE CONTROL ON-OFF SWITCH IN THE DASH, IT RECEIVES A DATA BUS COMMUNICATION
MESSAGE VIA SAE J1939 DATA LINK BUS FROM THE VECU (VEHICLE ELECTRONIC CONTROL UNIT) WHICH HAS DETAIL "F"

ALL SWITCHES ARE MULTIPLEXED EITHER USING THE MUX SWITCH CONTROLLER OR RH STALK, EXCEPT FOR THE CLUTCH SWITCH BEHR/GENTECH COOLANT
