wiring an electric seat?

A 2003 GT should have a 4-pin 12V plug under the driver's seat as all GT's came with an 6-way power seat track and adjustable lumbar on the driver's side.

On the 4-pin plug are two large gauge wires, and 2 smaller wires. The 2 small ones are for the seat belt minder that connects to the driver's side seat belt buckle. The two larger wires are 12V for the power seat track.

You can use the 12V there to supply power to both driver's and passenger seat.
