A wire untwisting tool includes a housing having a wire gripping end, an actuation end and a cavity. A plunger is received in the cavity. The plunger is movable between a retracted position and an actuated position and includes a gripping head movable with the plunger between the retracted position and the actuated position. The gripping head is configured to hold the twisted pair of wires in the retracted position, wherein rotation of the housing in an untwisting direction untwists the wires.
