I just tried to post pictures of the coil and solenoid but couldn't get it to post.
So, just to give you a basic idea what to look for:
COIL- is hooked into the ignition system, when you have a distributor it is usually the
"sparkplug cable" in the middle of the cap, at the end of that cable is the coil
Solenoid- Usually mounted directly on the starter top, follow your positive cable (usually red) from the battery to the relay then down to the starter and you will find it.
If I can get these photos to upload you'll see better. Sorry
