MeyerPlows - Meyer Plow Main Wiring Harnesses Info The MDII made it necessary to unplug EACH plow light, the 3 individual Coil wires, and the Motor Harness to remove the complete plow assembly. Meyer came out with the 1 Piece Plug. The very first consisted of a short truckside harness that the individual wires could be plugged into, and a plowside harness that would connect to the E-47H, E-57H, or the E-60H.
