Download Harley-Davidson Heat Demons Installation Guide – 1. Remove the Right Handlebar Control, upper and lower switch housing screws, and Right Grip from the Handlebar according to the service-manual instructions and set aside or leave hanging. Remember to insert a spacer between the rear brake light switch and the lever to keep the switch from being broken. 2. Remove the Left Hand switch housing from the handlebar according to the service-manual instructions. 3. Using a T27 TORX drive head remove the half of the clamp that secures the clutch hand lever to the handlebar and discard. The Heat Demon controller will replace this clamp when finishing the installation. Separate the clutch hand lever assembly from the handlebar and move away from the bar. 4. Mark the location of the Left Grip and remove it by twisting, heating or with air pressure. Almost all grips can be removed without damage. If this does not work it may be necessary to cut the grip for removal. 5. A hole needs to be drilled in the bottom of the handlebar to route the power wires and wires from the Controller. The location of the hole should be in the groove or recess on the bottom of the handlebar under the Left Switch Housing at the end of the groove toward the grip.
