NOTE: 
IN THE ACTUAL VEHICLES, SOME OF THE JOINT CONNECTOR TERMINALS 
IN THE SAME BUS ARE USED, SO IN SOME CASES, THE TERMINAL ARRANGEMENT 
INDICATED ON THE CIRCUIT DIAGRAMS DOES NOT AGREE WITH THE ONES IN 
THE ACTUAL VEHICLES.
HOWEVER, ON JOINT CONNECTOR (CAN1, 2, 3, 4), THE TERMINAL NUMBERS INDICATED 
ON THE CIRCUIT DIAGRAMS SHOULD ALWAYS AGREE WITH THE TERMINAL ARRANGEMENT
