Detailed Product Overview

This Standard Ignition transfer case motor, part number TCM109, is designed for vehicles that rely on an electric actuator to shift the transfer case between drive modes. It is a fitment-based replacement for 2008-2011 Ford Expedition, 2009-2011 Ford F-150, and 2010-2011 Lincoln Mark LT. The unit uses a female connector, 7 male pin terminals, and a round/square connector shape for the specified application.
