[Sintron] Arcade Jamma Board Standard Cabinet Wiring Harness Loom 282 56pin Cable for Arcade Jamma Multigame Boards PCB Video Game Board

No documentation. Parts/Solder side not labeled. No key inserted to make sure you don't install backwards. Weird unlabeled 3 pin connector w/+5v,+12v,gnd connection. No wire for video ground, instead they wired that to main ground. Took hours looking at JAMMA pinout sheet. Good thing I didn't just plug into a board. You're better off spending some extra cash on a labeled harness.
