simple job, cut and dry small cables, but how the hell is the easiest way to change the back passenger cable (i forget the sequence) but from what i can see you have to go from under the car, around the cat, and then pull like hell to get it off. then replacing it just feel with your hands and find the sparkplug.

is there an easier way without taking anything major apart?
