My 99 has drivers power seat but not the passenger. I want to install the power/heated leather seats out of my donor 2001 truck. They are the exact same truck. Can I just take the wirering harness out of the 01 and run it in my 99? Or is it ran into the main wirering loom? I know I can just run a power to batt with fuse but what about the heated switch wirering? Seatbelt modual run with it? Just trying to get a heads up before I tear it all apart.
