a weight not shown may be placed against the top most wire of the stack 36 to urge the stack downwardly a rotatable wheel 40 arranged on an axis parallel to the axis z has a peripheral edge 42 which abuts the lower most wire 16 and thereby supports the weight of the stack 36 a second pair of rollers 44 are arranged directly under the holder 24 and have their rotational axes parallel with the axis z a notch 86 is disposed in the periphery 42 so that as the wheel 40 rotates the notch 46 pauses directly under the stack 36 so that the end wire 16 will drop into the notch as the wheel 40 continues to rotate the wire 16 brought into engagement with a contact 50 which pierces the insulation and makes contact with the conductor of the wire 16 by a method that will be described below the terminal 22 that is to receive the wire 16 is determined thereby determining to which side of the connector 20 the wire 16 should be directed the wheel 40 is then rotated in the appropriate direction to place the wire on the desired side of the connector 20 rotation continuing until the notch 46 is positioned downwardly as shown in fig1 a pusher 48 is then inserted through an opening 52 in the wheel 40 forcing the end of the wire 16 to engage the rollers 44 and be pulled downwardly and back toward the clamp 26 until the wire engages a wire.
