How do you adapt the existing wiring harnesses to accommodate an upgrade to factory heated and power seats?

Answer 1

What year is your vehicle, and what year vehicle are the seats from?

If your vehicle was designed for heated power seats there should be an open port for the harness and relay. The proper procedure is then to aquire the stock harness and wire bundle (check a junk yard), plus the correct relay and fuses. Route these wires in the factory clips ( there should be a molded plastic channel for all wires in the floor near the center column or kick plates) and through the precut locations in the carpet. Plug them into the new seats. Plug the relay into the factory location. Add the fuses to your fuse block. If the heaters require a separate switch on the dash there should be precut locations with plastic slugs in them. Punch out the slugs and replace them with the switches. Test the seats. If they do not work consult a professional installer.

If your vehicle was not designed for this option contact an MECP certified car stereo installer and they can wire this for you.

I would charge around $300 in labor, plus the 15% over the cost of any parts. You would be looking at a fee of $450 or so through my shop because this is about 2 hours of work (really only about 45 min if precut by Jeep) after I get the parts. Best case is a full business day, likely 2 because of parts. Believe it or not, that is pretty fast and cheap. A dealer will probably charge around a grand and have your vehicle for 3 to 4 days minimum.
