A connector includes sheet metal contacts (40, 42) with termination ends (60, 62) for terminating to wires and with mating ends (70, 72) for mating to other contact devices such as circuit board pads. Each terminating end includes a wide groove part (90) with a groove bottom (94) that receives the wire insulation and with a pair of wide groove part wings (96, 98) that are crimped around the insulation. Each termination end also includes a narrow groove part (100) for receiving a bared conductor of the wire, the narrow groove part having a bottom (104) that is offset from the wide groove part bottom (94), and the narrow groove part having a pair of narrow groove part wings (106, 108) that are crimped around the wire conductor.
