Can you show me a pic of what you did? I need to do the same for my POTC. I have so much mods attached to the 12V that now I don't think I can connect my 2 Noflix Pinball Cards on there. They each draw 400mA (about 1/2amp) so I just ordered a 120V-12V power supply. I was going to used the service outlet also but I was also thinking if attaching another switch to it and drill a new hole on the bottom of the pin for the switch. But now i wonder if I can just tap into the 115V for the validator also. I just hope it can handle a but over 1 amp.
