Our 920D Custom S5W-HSS harness is designed for strats with a full sized humbucker in the bridge position. It features a 5-way super switch that automatically splits the humbucker when combined with the middle pickup (position 2). It also allows the single coil pickups to "see" 250K volume control while the humbucker "sees" 500K volume control. This wiring harness is a must-have for your HSS strat.
