ok I have 2 connectors under the dash on the drivers side both are 2 wire connectors but are not plugged in to anything. one is on the left one is on the right side of the steering shaft. they look similar (but so do most 2 wire connectors on this truck) I have the auto head lights and fog lights as well. was there an adjustable pedal for these?

 

These trucks in general ? Yes there was. Not sure when the F150 got them. I know the 2001's had them.

 

My 2001 has adjustable pedals. I have the shop manuals at my office. I could look for the diagrams if you need me to.
