Ok so i've noticed that on a few of the 03 model FX4's and King Ranch models they have digital heater controls along with the indash cd changers. I've found a wrecked truck with the digital heater and ac controls and im curious if they will fit in my 01 with turn ***** or what type of probs i would have trying to change them.

 

nope. you will need extra electrical wiring to make it work, IIRC. I have looked into this myself, but after seeing a few pictures of the back of the digital control housing, there seems to be a few extra plugs/harnesses, and no vacuum tube...

 

here is a picture I was referring my information to...
