seat swap

was wondering if anyone has went from non power seat to power? How much trouble it was .have 03 silverado everything else ive put on it that wasn't on it when i bought it the wiring and everything else was already there was wondering if this would be true of the seats?

I dont know on yours but I did it on a 1990.
All I had to do was run the wire under the carpet to the fuse box the a a spare 20 amp outlet. it took ten minutes. I have had it installed for two years with no problems at all and is very comfy.
