LOCATING THE AUXILIARY
SWITCHES
The auxiliary switchboard on the overheadconsole makes aftermarket customizationeasier with six prewired switchesconnected to the power distribution box.The circuits are individually fused forconnection of electrical accessories.
The switches have labels for AUX 1 throughAUX 6. They only operate when the ignitionis in the on position, whether the engine isrunning or not. We recommend that youleave the engine running to maintainbattery charge when using the switchesfor an extended time or when using highercurrent draw accessories. When you turnon a switch, the indicator light on theswitch illuminates and the circuit providespower to the device wired to that switch.
Note:AUX switch 1 operates the off-roadlamps when your vehicle comes with thisoption.
