headlight switch functions?

[foxfab]

My headlight switch is FUBAR. What should each function be? There seems to be two clicks left of center and one click right of center.

Also, what switch should turn on the light under the dash?

Picture from that handy owner's manual posted in the factory lit section. ;p

There is no separate position for the underdash light, it comes on all the time in position 1 & 2.

The position to the right (3) is for convoy - tail lights only.

Position 1 is everything except the front parking lights.

Position 2 is everything except the headlights.

Stock setup was a little too funky for me. Somehow I wired my front parking lights to be on in both 1&2 I'd have to look to figure out how. Maybe I'll move the underdash lamp to come on in position 3.
