For almost all cars, the negative is the ground, and wired (grounded) to the cars frame / chassis. White plug is a term used to describe the type of cable end which is used to connect two electrical devices. Answer: The positive wire (red) is called hot because the red wire (called positive based on current flow convention) is the one that connects to the hot wire of the electric panel in the wall receptaclethe source of electric field, energy, or power from the electric plant. It matters where the wire goes because if you connect the hot wire to the neutral terminal and the neutral wire to the hot terminal, you will reverse the polarity, a phenomenon that can lead to electrocution. Positive vs negative wires in power cable - DIY Home Improvement Forum Solid color wire and striped wire is negative. The side of a plug that is typically identified as positive is the side that has a protruding metal pin. Instead, the two prongs have a 'hot' and 'neutral' side.
