2021-14 door panels into 05-09 mustang. I have searched and tried to look into this as much as I can, so I apologize if this annoys anyone. I know most people cut the door panel switches out of the 05-09 and install them / glue them into the new panels. I am sort of not sure about how I feel about doing that, and was wondering if anyone had tried to rewire the new door switches into the existing vehicle wiring. If I cant do so I will go the other route, just wanted to look into my options.
