Well unless you’re replacing that monitor with the same make and model monitor, you’re most likely not going to have plug & play joy. From the pic the video signals plug into the bottom left corner (green molex). Does not look like the red molex coming from the game PCB will fit. So you have to hack the video cable. Just match the wire colors to the inputs on the chassis. They will be labeled on the chassis G = Green, R = Red, etc. The way you connect it is up to your skill. As far as the power goes, the best I can tell it’s the green molex on the bottom right. It should have a fuse immediately after the input. Some different pictures of the monitor would help.
