well, still nothing from nobody that seems to have anything to add, but i'll keep going. i have a 2013 2500 suburban - KB6 wasn't an option. i have heated and airbag seats from factory. i have procured the identical seats with the addition of the cooling option as well as the door switches. i have identified that there are two wires from the truck (B10 and B11) in the truck-side harness (X303) that don't exist in my build from the factory that the new seats will need run. i am working on locating the schematics that will tell me where these wires come from...
any help would be GREATLY appreciated!
