I'm thinking about doing this same mod. I lucked out and a uncle of mine who goes to garage sales regularly picked up a bunch of Hallmark Star Trek ornaments for real cheap and luck would have it that he has all the ones I need for my pinball. He's selling them to me for 15 bucks for all of them. Anyway, I'm not the best with wiring either so I am trying to find a step by step tutorial but one of the links posted above doesn't work and the other has pictures that really aren't clear.
