you have to pull the wire off. pull the metal pipe and spring off with the wire if you can. its for heat shielding or something and over the boot. id put it on the new wires if you got some. then get the right socket and ratchet and remove the plugs. i know on the 97-03 you have to rock the engine fwd to get to the back ones. it made it so much easier. i just did plugs and wires on mine. let me know if you need anything else.
