I want to add heated seats to my 06 FX4. Currently I have the standard heater controls and would like to replace them with oem auto climate heater controls that have the heated seat buttons. This has the LED reading which I currently don't and and so has push buttons for air control such as face, legs or both where currently I just turn the ****. If I find the auto climate set up is it just take the old one out and put this in?
