Have the system on my Electra Glide. The bike comes with the system disabled from the factory. You enable it by turning on the ignition switch, turn the off/run switch to run(do not start the bike). Push the throttle to the roll-off position and hold for approx. 3 seconds. The cruise indicator light will turn green for enable. Repeat process to disable(light turns red). There is a difference in idle and a unique exhaust odor, both are considered normal.
