4th Gen Dash Into 3rd Gen

[uTweaker]

Hey, First post on here!
Currently in the middle of a interior swap

Just wondering if anyone knows how to get the 4th gen 4wd switch to work in a 2003 5.9

I know that the headlight switch wont work unfortunately, but I heard the 4wd will. Just not sure what to do right now

Or if anyone has the wiring diagram for the 4wd switch?

Would like to do the same and seats as well in my 06 Mega Cab.
