The p/s you have there is fine but the suzo wayout ^^^^ has is better because of the 12 volt section can be used for leds strips and other 12 volt mods. I rewire the service outlet on my pins so that the outlet turns on with the power switch.

That means you can add many more mods.

Either way it wont matter. I you like I can take a pic of how I rewired my No Fear service outlet to be on only when the game is on. It will have to be later as I'm still at work.

Not a stupid question.

Yes.

Do you mean a negative signal and positive from your new power supply? If yes then good to go.

Yes, tie to the ground braid in the cabinet. Also make sure lower cabinet ground braid is connected to the ground in the back box.

He wants to make sure your you don't put the positives voltages together. Like connecting new power supply 5 volts to the game 5 volts on the driver board. This is bad!

Egon knows his shit.

True, but only if he uses a three prong cord. I sure hope he does uses a grounded cord for safety.
