Interior upgrades

[Blaise]

I want to upgrade the interior my 2011 Chev 3500 extended cab which has basic work truck seats. I found a nice set of leather powered and heated seats at the salvage yard. I know I would need the door panels for the switches and harnesses. Do I need the harnesses going th o the seats which are under the carpet and should I also get the BCM from the truck to make it all work? Bought the truck as a non-runner and got it up and running now want to dress it up

Probably need the harness if it didnt originally come with all the options that the new seats have.

I got the floor harness but the plugs are different at the dash, I still have access to dash harnesses but wonder if they will work since it is a LTZ dash in the truck I am getting them from
