The plugs are a different size, and therefore the shelf is different as well, if you try and put the 19 pin connector in the bracket of a 25 pin shelf (or 25 in a 19) they won't fit

Do you have the pin out for the 25 pin plug?

There is one caveat. The monitor I want to power up is a Ceronix.
So before applying any power I unplugged the machine and turned it on then ohm-ed out the power plug pins to the AC power pins on my test cable and got zero Ohms.
Which meant there was no isolation transformer in the machine - it normally runs with a larger, non Ceronix brand monitor, which apparently had it's AC isolation built into it.
This is why the Ceronix monitor has it's AC power pins in a different location.
Pins 18 and 19 are used for AC power. I'm going to install a isolation transformer and connect pins 18 and 19 of the 19 pin monitor plug to pins 24 and 25 of the machine side connector and put a big red flag on it saying "for Ceronix only - must use isolation transformer".
I'll make a second cable for non-Ceronix monitors (pins 14 & 15 to 24 &25).

note pins 18 and 19 have 250 v ac form 13" game king uprights slant tops Bar top and the 19" uprignt
the 17" games and the 19" slant top are using 120 v ac and the ceronix 17" and 19" have the isolation transformer in side the monitor
and the lcd monitors don't care will work from 100 to 250 v ac
