hey guys wonder if anybody could help or have done this. i have a 04' screw fx4 with the manual controls. i have the lariat(digital controls) to install in my truck. one plug will work and the other won't. is there a pic or diagram that somebody could post to swap the wiring so i can use these digitals in my truck. thanks for the help. jason

 

You need more parts. There is an additional control unit and various sensors that the manual system does not have. The manual system is based on **** position not actual temp and is a vacuum controlled mechanical system.
