Run a wire, through a fuse to the underside of the seat. Most seats have all the relays built into the seats harness, you should, just need power. I'm willing to bet, if you dig hard enough, the fuse block already has a powered fuse port w/o the fuse and wire that goes to the seat. I don't believe the seat power would be relay controlled since the seat adjuster works when the truck is off, but the seat switches would be, and (again) built into the seat.I am adding power seats to a non power seat truck. I only have one wire for the seatbelt indicator and that is it. How can I wire up my seats? Thanks in advance!
