Electrical Tapping, Newbish Question Options

[LeonStryfe]

I made a switch and I need a way to connect my redwire to a 12V power source.

1st Question - Which area inside the car should I tap into? Lighter Socket?

2nd Question - How exactly do I tap power from something? Ie- Parking lightsfor Fog, switch to lighter socket etc. What do I do?

To make an example, say a neon tube with switch set up.

The switch will have 3 wires, one will be grounded, another will be connected to the neon tube (while the other wire from the neon tube is grounded) and the other wire should be connected to a power source. Now how exactly do I do this?

Clip off the plastic covering of a positive wire (say for example - parking lights or lighter socket) and wrap the copper together and wrap it around with plastic covering?

Sorry for such a n00bish question

Use a soldering iron to make a proper connection, then seal it of with some insulation.
If you just wrap the copper together, it may get loose because of the vibrations in the car
