A friend who owns a salvage yard recently got a 2003 truck like mine in as a total. I want to get the power seats and put them in my vehicle. Mine does not have power seats. I need know if this will work, if so...I need wiring diagram for the seats. Can anyone help me with this?

Why not just rip out all of the wiring from the wrecked truck and replace it and hook it up the same way in your truck? It couldn't be that hard...

you need the harness from the seats back to the dash, and from the fuse box to the firewall.

Buy the schematics for the truck online, and wire it yourself, without the harnesses.
