There can be up to six auxiliary switches located in the lower switch bank of the instrument panel which can be used to power various electronic devices and Power Take Off (PTO). If equipped, it will take the place of the sixth auxiliary switch. Connections to the switches are found under the hood in the connectors attached to the auxiliary Power Distribution Center.
You have the ability to configure the functionality of the auxiliary switches via the instrument cluster display. All switches can now be configured for setting the switch type operation to latching or momentary, power source of either battery or ignition, and ability to hold last state across key cycles.
Holding last state conditions are met when switch type is set to latching and power source is set to ignition.
