I just got a 06 f-250 SD. There are 4 AUX switches underneath my radio, what are these for and where are the hookups for these.

Thanks

 

Those are Upfitter Switches. They are used for anything you want.

 

The hookups are directly behind the fuse panel. You can get to them from underneath or you can unbolt the fusepanel and pull it forward to get better access to them.

They are for whatever accessories you might want to add to your truck.

 

Yep, right behind the fuse panel....4 orange wires all taped off.

Here's a pic (the white wire with the red rings is the wire to trigger my aux. backup lamps).
