Well I have been told it is easier to remove the kick panel but for me personally removing the gas pedal made the wire more accessible.
The only thing with getting the gas pedal off is the washer once you have removed the nut.
It must be removed with a magnet.
It just fits to tightly to simply pull away with the pedal.
Once off though drill a hole in the washer slightly larger and it will not be a problem if you ever need to remove it again.
