Type B Systems (Description
This system will have a switched wire that goes to (-) ground as the switch is operated, and another
wire which will remain at (+) 12V with ignition. The wire you want to cut and interrupt is the
wire that does not change state, but remains at (+) 12V ignition when the switch is operated in the
desired direction. Remember that using the relay as shown in the diagram effectively changes the
Type B circuit to a Type A circuit only during module activation.
