So I have a b5 1.8t facelift model. I'm looking at buying a set of s4 seats. They are heated and power. However my current a4 doesn't have heated/power seats. If I replaced the climate control module and tore out the old seats, would the wires still be there for heat/power for these new seats or will I have to run wires myself?

I would say have to run the wires bro
