Quoted from vid1900:
This is the correct installation of the Coil; Diodes safely away from the Coil Stop. It matters, do it right.
Some Coils were installed backwards at the factory, so you may have to pull a little slack wire from the harnesses to reach the proper position. Don't worry if you have to clip a few nylon Zip Ties to produce the slack you need.
If there is a little plastic nipple on the coil, you can cut it off, or cut a little notch in the coil bracket with a Rat Tail File or Dremel.
So this may be a complete newbie question, but do I need to change the wiring when connecting back to the game, does turning the coil around make the plunger want to go in the opposite direction?
