Ok, here are the pictures of what I'm working with.
The new lcd has a place for a plug but it didn't come with said plug or pig tail, there is also a picture of the model number of the lcd.
There is a picture of the power wires going to the crt monitor that I won't be using because the lcd has its own power brick. Then there is a picture of the wires going into the board of the crt, now this plug may or may not plug onto the lcd, but I don't know if the orientation of the wires is correct. And speaking of those two plugs for the monitor on the crt it has a locking lip that goes across the whole width of the plug, on the lcd each prong for each wire has a separate prong for the wire to clip into. It seems it would be impossible to lift up every plug at the same time to unplug it if I needed to, plus I don't want to break anything giving it a try..! Then there is a picture of the old power supply, isolation transformer, fuse panel and an on/off toggle for power.
I did look at the new harness and it was made by Happ which is the same company that made the power supply so the plugs for power, board, and game play buttons are there.
I'm just stuck on the monitor and later on a bill acceptor...!
