Knowing these connections is vital for several reasons. For example, you'll need to identify the constant power wire (which provides power even when the ignition is off) and the accessory power wire (which only powers up when the ignition is on) to ensure your new stereo turns on and remembers your settings. The importance of correctly identifying these wires cannot be overstated.
