So I've been working on arcades for a little while now and so far Ive dodged really having to do anything to the monitors. Its really just been taking them out recapping and putting it back in just like it was. Well I just got a 25" k7400 that I think Im going to put into a hs-5 Im building. The cabinet is being built from scratch and I will be wiring myself. Its my understanding that the k7400's do not need Isolation transformers so to get power can I just take a cord strip the end and put the correct plug on black to load, green to ground, and white to neutral (see pic)? Now the video is a 9 pin plug on the monitor. The jamma harness I have is 5 pin. Is there an adapter for this or is it something I need to make? What are the other 4 pins (see pic)?
