02 cloth to leather seat wiring

[BWC]

My buddy and I installed some heated leather seats in his 02 and replaced the cloth seats. My question is will the factory that comes out of the floor work with the leather harness?

I know the connectors are different and I believe that the wire colors are too.

Also I haven't looked but behind the dash where the heated seat buttons go is there the two connectors to plug into the buttons?

Thanks in advance
