Hi

I have a line on a full set of leather seats(front buckets and rear bench from a bone yard, out of wrecked 2004 Jimmy. The driver seat is power. Problem is that there is no wiring harness/wiring under my current seat and I think I can run power to it. I have the wiring diagram out of my Haynes manual and it says that the seats are powered by a 20 amp in Fuse block marked "Power accessories Circuit Breaker A". Is that the fuse block in the cabin or is it the one under the hood? Also if I have to run a wire into the cabin from under the hood, what would be the best route to take?

Thanks in Advance
