I wired it according to my diagram and it actually works! Amazed at this moment:
Remember to cover those bare wires up with something, heat shrink or electrical tape is the only way to go. Take your dremel (or anything that can cut a tiny hole) and drill a hole big enough for the switch to fit through. I screwed the switch into the faceplate where my other switches are to make it even:
The neon switch is the huge one to the left, purposely done to not get myself confused. Now for the test run, lets see if this thing can put out some glow:
Alright! Nothing toasted, glowing quite well. I screwed the tube to the left of the case so it doesn't block any tinkering I may want to do with my system. You can add more tubes in different areas just as long as your PS can support it. Hope this guide helped, let me know about your neon projects!
