As always, if you 'integrate' your mods into the electronics of the game, you run the risk of blowing up your $7,000 pinball.

Not recommended.

There is a 110v power source behind the silver plate underneath your power supply in the backbox.

It's a two pin plug, capped with a two-pin orange jack that doesn't have any pins in it. Unplug the power plug on the back of the pinball. Take the metal covering off by using an 11/32 nut driver on the back nut behind the service outlet (which you could use, but it stays on whenever the pinball is plugged in, not just when the pinball is turned on...). Then remove the nut right above the fuse holder.

The other nut is in the upper right corner of the circuit board with the caps. Then the metal plate can be removed and you can dig out the orange plug.

You'll need some .900 pins, about 18" of lamp wire (18ga). And two 1/4 inch terminals. Put the .900 terminals in the orange part of the connector, extend the wires along the bottom of the backbox, and close up the metal box by returning the 11/32 nuts.

Put 1/4" terminals on the other end of the lamp wire, and use some large diameter shrink wrap over the terminals (115v shock hazard here, be safe!).

The two terminals slide onto either your power supply, or sometimes I'll get a 3-to-1 power outlet.

Do something like THIS to power your mods, and if your LED strips short out it'll only take out the LED power supply, not damage your game.
