This is for all three plugs from the 'World' plug configuration. An original factory 20-pin square auxiliary plug, the main 16-pin rectangular plug and the 8-pin small square subwoofer plug (all with wiring pigtails). The auxiliary plug is used for the factory inputs such as rear seat audio, steering wheel controls, CD changer, etc. The main plug is used for power, ground, illumination and primary speakers. The subwoofer plug goes to the factory subwoofer. These would be spliced into your existing harness if your factory plugs have been removed from the vehicle.

*Not all models had this plug style in all the years listed. Please check your radio before ordering. This style of plug was used in many 1998-2007 Ford vehicles without Premium Sound. This is not used in the 2004 and newer F150, Expedition and Navigator.
