IMPORTANT: This circuit is used if the customer has
purchased a tire position switch from the equipment
vendor. The switch enables the Controller software to turn
equipment on and off as each of the vehicle's tires pass that
piece of equipment. In order for this to work properly, the
tire switch should be located in line with the gate switch.
