Thanks for your reply, Ian! I made a mistake. It is on arcadeshop.com, not
arcade. Unfortunately they don't provide any other info than the following brief description and image.
/DK Jr./Donkey Kong 3 Wiring Harness and power supply solution (complete solution)
All wiring needed to hook up the pcb. Note: +24 vdc is not supplied for the coin counter.
http://www.arcadeshop.com/pics/kong-harness.jpgI'm basically just trying to find a nice clean way to hook up my dk pcb to my sanyo ez20 while having all new cables. A new power supply would be nice because im really not sure if the original one found in the cabinet works, or will last a long time, etc. I'm happy to buy new parts for the peace of mind.
Thanks!
