Tire Switch Wiring

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.
The following diagram shows how to wire the Tire Switch (tire position detection) into the Relay Box.
