I have an 03 f350 single cab xl and I want to make it into an XLT. I already replaced the bench seat with two new captains chairs but that was the easy part. The power door locks windows and mirrors is what I'm concerned about. I have two full spare doors complete from and XLT sitting in my garage just don't really know where to start. Anybody done this before? Is there wiring already in my xl for the power windows and door locks or am I going to have to run all new wiring? Any information would be greatly appreciated.
