I bought the digital a/c controls for my '07 to put in but one of the wiring plugs on the back is different. The other plug is the same and will work all knobs, buttons, etc. I think the other one is what actually makes the a/c/heat turn on and that is the one that is different. Has anyone done this and made it work? I got the controls cheap so that's not a big deal, but I would like to change it over if possible. Thanks.
