What kind of car are you trying to put it in? There are many different cars out there that require the use of an antenna adaptor to make it fit the standard "motorola end" of the aftermarket stereo. The Alpine needs to "see" 12 volts constant power on the yellow wire and 12 volt switch (key on) on the red. Good luck
