Hello guys i have 2007 xlt f150 and when i took off the dash cover i noticed there was a plug with red black white and red/blue colors on it just hanging out under the dashboard next to the dimmer controll switch, any ideas were it goes to? Thanks

 

That's probably the wiring harness used on trucks with power-adjustable pedals. If I remember correctly, the dash cover has a blank spot that holds the connector.
