Moisture causing corrosion on the nutted wires causing a high resistance on the splice which in turn creates heat. Sometimes on conditions like this the wire insulation can melt back up to six inches. Close to the splice the insulation can actually get so brittle that it will fall off of the wire.
For a 12-2 wire (which consists of a black insulated wire, a white insulated wire, and a bare copper ground wire), you should use a red wire nut. This wire nut size is designed to accommodate two to three 12-gauge wires, which is suitable for connecting your 12-2 wire.
No, Plastic is not conductive! I other words plastic can not conduct electricity therefore it can not produce resistance, and resistance is what you need to produce heat. and that heat would melt the plastic. Now if you touch a "live" wire to metal and that metal was grounded ( for example to a cold water pipe) then you would be completing the circuit, then that piece of metal would heat up very rapidly and eventually melt! of-course the smart person would not do this but if you where not so smart be prepared to get burned!!!! BE SMART!!
The color of a wire nut typically corresponds to the size of wires it can safely connect. Different colors are rated for different wire gauges and combinations. It's important to always use the correct size wire nut for the wires you are connecting to ensure a secure and safe connection.
Cap the extra wire with the appropriate size wire nut so that it will not short out against grounded objects.
Connecting different gauge wires are just like connecting wires of the same gauge. Connect the wires just as you normally would, and then once the you attach the wire nut, give the thinner wire a slight tug to make sure the wire is securely fastened. Usually when attaching fixtures, they are generally stranded wires. Be sure to twist the strands together before twisting them onto the solid wire. Then attach the nut onto them and tighten it securely. Connecting different gauge wires are just like connecting wires of the same gauge.

Short in the circuit or the circuit was overloaded.
there is not a proper grounding wire mounted to the body of the car or truck.
A wire nut can typically accommodate 2 to 6 wires, depending on the size and type of wire nut being used.
To properly connect wires using a wire nut with pigtail, strip the insulation off the wires, twist them together, and then twist on the wire nut securely. Finally, attach the pigtail wire to the wire nut to create a secure and reliable connection.

Something is shorted to ground on that circuit

A positive wire is grounded out to the frame someplace on the car. Best take it to someone else to get it fixed.
The most common way of making an electrical connection is with a device called a wire nut. Solid wire connections should be twisted together with a pair of pliers before installing the wire nut to hold the splice tight. Twisting stranded wire together with a pair of pliers does not allow the wire nut to grip the wires as tight as it should. Stranded wire should be held together side by side (in parallel) and let the wire nut twist the wires together to make a solid splice connection.

Sure. Just cap it off with a wire nut.
