Hi,

I am not sure I understand what you are trying to do. Are you trying to rewire your vehicle so that you can use a different control module?

If so, what is the control module out of? What model and year of vehicle is it? Thanks

Okay. I understand now. Unfortunately this is not going to just plug in and work or even if you rewired it. You are more than likely going to have to change the wiring harness and have the sales codes changed by a dealer so that the other modules know that this is now different. I attached the wiring diagrams from each system. Clearly these are very different. The problem is your vehicle has what is called a CAN bus system. This means that each system shares its info with each other module so you will have to program the vehicle so that all other modules know what HVAC module is in the vehicle.

Sorry I don't have a better answer but I see this as being a large undertaking.
