trick...neon has a main power and a ground...you must run the black wire (green) to a ground..and run your power (red) threw a switch...if your not sure about wiring a swtich...all you do is buy a simple 2 way switch in the case you run your power ( red wire) to the switch and run another wire from either your fuse box which has either a constant power or one that turns on with ignition...its so you can turn it on and off when ever you want...do you really want it on all the time??? sorry i didnt tell ya where to ground...a ground you will just need to take a ring terminal...like $.5 cens at your local hardware store and drill a hole and put a screw threw that ring terminal so you have a solid ground connection....
