4 Knob Control Layout

Pre-wired harnesses include battery clips and an output jack for quick installation. All of the pots are grounded with a wire that can be connected to the cavity shield or simply cut away if not needed in your installation. Knobs are a personal choice, so they are not included with the harness - except where there is a stacked (concentric) pot, we include a ring knob and center knob since they are not as common.
