yep, it is. it's for the arcade 1up modified hdmi controller. I wanted to move it to a new position so I could always access monitor controls, but it was too short.
I finally found the gauge of wire it used, so I will order some of that andsee if I can't extend it a bit .
Decided to go to the office today and get some stuff done. as I will just sleep the day away with nothing better to do. all the cables are in their proper places...except for two I'm not sure on. J805 and J 504 so this back box is ready to go back on to the machine.
