The trim is connected by some plastics push type hook-on's (three) to the underside of the seat. Just pop them out and voila. Also, you have one electrical connection on the passengers side and two on drivers side. I disconnected everything by first removing the four bolts on the seat and then tilting the seat back. This made access to everything much easier. Also, heard rumors that you shouldn't switch the ignition key to on when the electrical parts of the seat are disconnected; it would trigger an air bag light. I had to take out the seats for some extreme soundproofing.
