Replaced the plugs today and had 3 of the 4 Ignition Coils separate at the rubber boot (Red Arrow Below). There is a small terminal (looks like a solid copper fuse link) that sits inside-between the top of the coil tube spring and the actual Coil/housing. Luckily it landed next to the spark plug hole when everything separated. With all pieces disconnected and removed from the spark plug (Top of coil, connection fuse link, and rubber tube assembly) re-insert the terminal (loose) link so it rests on top of the spring then gently twist and allow it to pop back together.
