An electrical connector assembly for a fuel injector includes a receptacle and mating plug. The plug is formed with side channels within which socket contacts at the end of an electrical wire or conductor may be snap fit. The receptacle includes side loading wedges aligned with the side channels of the plug to place a lateral load or compressive force on the socket contacts. The plug is formed with strain relief wedges that place a vertical load or compressive force on the socket contacts or wire insulation and conductor held therein. The plug and receptacle are formed with a key and keyway for proper orientation. An external latch on the receptacle captures the fully inserted plug.
