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. Start by punching a hole location with a center punch to pierce the chrome. Use safety glasses that completely cover the eyes to protect from steel chips while drilling! Start with a small drill like a 3/32″ size to make the initial hole. Then use progressively larger drills or a step drill to increase the hole size to 5/16″. After the hole is drilled use a round file or deburring tool to remove the sharp edges. 6. Uncoil the plastic snake from the kit and run it from the right end of the handlebar out the left end. Twisting the snake or inserting it vertically versus flat can help to push around the corners. 7. Attach the white and yellow wires from the Right Grip Heater (Item 3) to the hole in the plastic snake and pull them through the bar so they exit the left end. (See drawing below) 8. Push the right heater into the handlebar by squeezing it together and sliding it fully inside of the bar. The end of the heater with the orange cap should be pushed in first. Cut the white and yellow wire to extend 4 inches beyond the left end of handlebar. 9. Install the Right Throttle Control and Grip according to the service manua

End weights or other need to open the ends: You may drill out the outboard ends of the grips for installation of end weights or other purpose, if you use a fine tooth hole saw and do not go larger than the handlebar’s inside diameter. We have molded in a visual guide on the grip’s ends, and we recommend 7/8″ or at most 1″ diameter and be sure to center drill carefully. DO NOT use a hacksaw or you will destroy the grip, because there are resistance wires molded into the grip outboard of the handlebar diameter. Some Harley throttle sleeves are molded with raised plastic ribs or ridges to help hold the original Harley grip in place, and these will mate up with four (4) of our internal ribs by sliding our heated handgrip over the sleeve. HOWEVER, there are two axial ribs, which go circumferentially around the throttle sleeve as illustrated below, and they may have to be carefully removed with a knife of razor blade. They must be trimmed off with a file or razor knife until the Hot Grips slides over them. Do not force the Hot Grips over the ridges as the grip cannot stretch and will be damaged if forced on. These Hot Grips® have a heat output of 8 watts on “low” and 15 watts on “high” per grip. As a pair they will consume 20 watts of electrical power on “low” and 30 watts on “high”. They consume more than 8 x 2 on “low” because the resistor consumes a little
