i just un hooked the battery when i changed mine. dont forget to unplug the seat, all plugs are under the seat.

once the seat is out of the way. pop the plastic trim at the door sill. the carpet loops over the inside edge with loop/hooks. take the foot cover off the lower dash pass side, the kick panel then un hook the carpet, then lift the carpet to the box you'll see under the rug. its bolted down with 2 10mm bolts iirc.
