4x4 HIGH/LOW RANGE Indicators
WARNING: This page is about a different car, the 2005 Ford Pickup, 2005 Ford F550 Super Duty, 2005 Ford F450 Super Duty, and 2005 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
The 4x4 HIGH and LOW RANGE indicators are both hardwired to the instrument cluster from the 4x4 control module when equipped with electronic shift, or from the 4x4 control switch when equipped with manual shift. The instrument cluster provides the 4x4 indicators with power and the 4x4 control module, or 4x4 switch, provide the ground depending on whether 4x4 high or LOW RANGE is selected.
