shift interlock switch for expedition

[travelin_farmer]

Hey,

My wifes 2005 expedition cruise control only works for about 5 min then shuts off and will not turn on. Pulled code P0581 (cruise control multi function circuit high) and after some searching online found others with this issue. They found the solution to the problem was the "shift interlock switch" in where the PCM thinks the brake pedal is depressed thus disengaging the cruise control. After searching I was unable to find anywhere the location of this switch other than "under the driver side dash". The part is less than 40 bucks but I have no idea where it is located. Anyone know of this part location? Thanks!!
