P-ROC PD-LED direct RGB harness.
This harness is used in Spooky Pinball P-ROC games to connect the LED driver board to the individual RGB LEDs, allowing 4 RGB LEDs can be controlled with 1 harness.
This is also a very useful harness for people using the P3-ROC PD-LED boards and RGB LEDs in their homebrew games.
