The GI in Williams System 11 pinball machines is controlled by relays, and when LEDs are installed, the results can be very abrupt. GI OCD allows you to customize how lamps are controlled in order to make them react more like incandescent bulbs, or just better in general.

This board works as a replacement for the relay board (C-11998-1 or C-11902-1) in System 11 games. There may be multiple relay boards in your game, in which case, you would need multiple GI OCD boards to replace all of them. You can, however, decide to selectively replace boards. For example, you may choose to leave the backbox relay in place if it does not bother you, while replacing one or two playfield relays.

GI OCD for System 11 is designed to be a replacement for the existing relay boards. Unfortunately, it is not plug and play. Installation will require tracking down the correct connection point yourself, desoldering wires, soldering new wires, adding connectors that are not included in the kit, etc. Only experienced modders should attempt this installation.

This product may not work well with "special" bulbs such as blinkers, color changers, etc. The most common result is that they do not blink like they should.

For configuration, you will also want one of these adapter cables.
