This is the Western/Fisher battery cable #63411. This runs from the motor relay and the ground side of the battery out to the 2 pin power plug on the plow side. It is the same for Western and Fisher plows that have a 3 plug wiring system. This is only used on the 3 plug plows. There is an extra ground wire coming out of the harness at the battery terminal to connect to control harness with a bullet connector. This will not work on the new 2 plug Multiplex plows. If you have a Fisher Extreme V, Western MVP Plus, the new Blizzard Power Hitch II or a new model of the Western or Fisher straight blades (2011 and later) with only 2 plugs, then you need #42014.
