Kind of random but worth asking. Our 2012 350 got hit on the driver's side. I got a salvaged 2006 door In the same color. Fits perfect, main harness plugged in, doors lock and the speakers play. However the window harness is totally different. There may even be 2 harnesses for the older door.. not sure. Lots more wires on the older model. A few ideas but would love Insight:
• Splice and rewire the 06 to the 12 If possible
• Swap the entire 06 harness in the door with the 12. Hopefully the others work the motor and lock?
• Find an 06 window switch but IDK if it will fit the 12 interior
• Maybe there is an adaptor (I doubt it)
Open to suggestions! TIA

 

JM2C - I'd swap the mechanical items they plug into unless they are damaged/destroyed. Even then, go to fleabay and grab some used ones. Otherwise you are diving into wiring schematics, re-pinning connectors, cutting, splicing, troubleshooting burned fuses and all that.

Swapping parts is just nuts and bolts putting it back the way you found it.

Maybe look the parts up for the two different years and compare the differences? Ebay is good for this type of stuff.

Oh and welcome to CL!

 

Yeah that was one of the ideas. When I look up the window switch it says it works on all these years so it's confusing. https://www.ebay.com/itm/37381753312...mis&media=COPY

 

Swap the entire harness over, and everything else electrical.
