2) I want to wire both my footwell neons AND make a switch for them...Do i just connect both wires under the drivers side firwire/wall and hook them to the battery? And how do i go about making a switch for them to turn on and off?
There are many ways to wire a switch, depending on what type of switch. For the simpliest switch, take the powers and run them to the power side of the switch and run another wire to a power source and attach to the same side of the switch. Then take the grounds and attach to ground side and run a wire from there to a ground source.
You can also run power directly to the neons and use the switch to control only the ground, or vise versa.
