Quoted from Darth_Chris:Since Steve installed it himself and I never got to see the pin before the Refinery job I can't honestly tell you. Contact Steve directly sure he will provide more details.
Got mine installed last night, and looks sick!!! The UV makes the back third of the playfield " glow" in a cool way ( and varies in intensity as it's tied into the blue flashers on back panel)...REALLY adds a dynamic feel to the mode.....
Only drawback is it will make you take your eye off the ball to watch the interaction....massive drainage follows shortly.
I'll post some video in action tonight so you can see it, as long as there is no blatant reference to how bad I suck at the game!!!...mark 
Hmm...maybe I'll shoot the video, and have my Son play.....
