Silverado Air conditioning mod!

[GasJobMafia]

In my 04 Silverado I have the dual climate control with the knobs and sliders, and I picked up a deluxe Air con Unit With the Screen in the middle and 2 knobs! The rear connector for the fan speed control is different but wondering if anyone has done this mod and knows how to splice the correct connection in! Ill post pictures if end up doing it!

I'm not sure if it would still work. Probably requires changes to the BCM.

So after a ton of research it requires quite a lot more work than I expected, Lots of temp sensors and what not that have to be installed around the truck for the auto air feature, but I'm more interested in just making the fan work with out the auto air, anyone soldered the to harnests together?
