Since we have some excellent knowledge here I thought I would ask here first.  I have a 2001 Silverado 2500 HD and I landed a pair of power seats also out of a 2001.  My truck doesn't have the plug ins under the seat so anyone know what I need to get power to?  These are not heated and it has manual lumbar.  Looks to have 2 wire plug on the passenger seat and 3 wire plug to the drivers seat.
