Have you been looking to upgrade your standard motorcycle seat, to a heated motorcycle seat but don’t have the extra cash? If you are able to run a staple gun, you can install Heat Demon Seat Warmers for much less than purchasing a new heated seat from your local dealer. K and G Cycles (www.kandgcycles.com) has just what you need, and our very own Operations Manager chronicled the install for you.
When the temperature drops, are you going to go home, or will you keep riding? Put a little heat in your seat and enjoy the riding season long after most other riders have called it quits. Heat Demon Motorcycle Seat Heaters offer an innovative warm seat experience for the riders who just refuse to quit. The universal fit carbon fiber seat heaters install easily on any bike, providing comfort and warmth for riders of all bikes.
For reference, all photos will be used while installing the Heat Demon’s on a 2008 Harley-Davidson Ultra Classic motorcycle.
Note: Heater is designed to be installed beneath the vinyl/leather cover of the seat.

Step 1: To get started you will need to remove your motorcycle seat. I would recommend that you connect the wiring harness to the battery first so that you can test the Heat Demons prior to installation. Your Heat Demon’s should have come with installation instructions, and the wiring diagram for the seat heaters. You can see Step 10 for wiring steps. I have also included the wiring diagram below in Step 10 for your over view of the wiring layout.
Step 2: Turn the motorcycle seat over to start the staple removal process. It is best not to remove all of the staples at one time. Using a small tipped flat screw driver, wedge it under the staples and slowly apply pressure. This should allow you to ease the staple from the seat and the leather. If you need additional help once the staple has been pulled halfway from the seat use long nosed pliers to complete the removal from the seat. I do not recommend only using the long nosed pliers, as this may cause damage to the leather.
Step 3: Now that you have removed the staples from the leather/Vinyl on the front of the seat, you should then be able to flip the seat over in the upright position and pull the leather back towards the backside of the seat.(See the examples below.) This should expose the foam of the seat. Once you have the foam exposed look it over to ensure there are no defects or problems with the foam. Also if the foam has a clear plastic liner between it and the leather, remove the plastic from the seat.
Step 4: To insure that you have 100% working heaters prior to full installation I recommend that you test these heaters first prior to mounting them to the foam of the seat. It is far better to discover you have a problem with the heaters now, then discover there is problem after you have already reassembled the seat.
Step 5: Once you know the heat pad does heat up, it is now time to install it on to the foam seat. You now need to consider where you want to mount the heat pad, as well as how you are planning on routing the wires. This is important so they are not visible once you place the leather seat cover back over the top of the foam. Once you’ve selected the route you want to run the wiring, slowly remove the 3M sticker off the back of the heat pad. Once the backing has been removed, place the heat pad (sticky side down) in the area that you would like to have heated. Make sure to press down on the heater to insure good adhesion between the seat and the seat heater. Note: A thin layer of foam may be placed over the top of the heater to reduce the visibility of the heater through the seat cover. Make sure to route the wires for the heat pad to the bottom side of the seat.
Note: Removing the foam and drilling a small hole through the bottom of the seat may make installation easier.
Once the wires have been routed so they will not show once the leather is placed back into position, you will need to ensure that the heat pad is flat against the foam. Next pull the leather cover back down into position, covering the seat foam. Once the leather has been pulled tight against the foam, this would be a good time to install 4-5 staples into the front section of the leather on the seat. However you do not want to put any staples within 6 inches of the area where you plan on installing the rocker switches.
Now that the front section of the seat is complete, it is time to prepare to insert the heaters for the passenger section of the seat. If you do not wish to install passenger heat pads, please go to Step 7:
Step 6: Next turn the seat over, and remove the staples for the passenger section of the seat. Again, I would suggest removing these staples with a flathead screw driver, and if needed use a pair of long nose pliers.
After you have removed all of the old staples from the seat, you now need to pull the leather seat cover back to expose the foam for the passenger seat. If this section of the seat has a thin piece of clear plastic, I recommend removing the plastic to only leave the foam section of the seat showing.
Step 7: Once you know that the heat pad does heat up it’s time to install the Heat Demon for the passenger section of your seat. Making sure the foam on the seat is clean of dirt. Now determine where the passenger normally sits on the seat, as well a route for the wires from the heating element through the seat to the bottom side of the finished seat. Again, it is best to conceal the wire so it doesn’t show once you place the leather of the seat back over it. This will eliminate any visible creases from the wire. Once you’ve selected the route you want to run the wiring, slowly remove the 3M sticker from the back of the heat pad. Once the backing has been removed, place the heat pad (sticky side down) in the area that you would like to have heated. Route the wires for the heat pad to the bottom side of the seat.
Once you are satisfied with the positioning of wires and heaters, pull the leather back into place. At this stage you do not want to install any more staples until the remaining steps completed.
Step 8: You are now ready to prepare the foam and cut the hole in the foam that will house the control switches for the Heat Demons. The standard position for motorcycle heated seat switches is normally on the left side, or port side of the motorcycle seat. For myself I found the easiest way mark the area to be cut, was to place the switch in the desired area and with a sharpie marker draw a line around the outside of the switch. This provided me a good reference point to use during the cutting process of the foam.
Step 9: Now that you have the area marked where you want to mount the switch, it is time to cut the hole out of the seat foam. Take a sharp razor knife/your favorite survival gear (click here to get one if you still do not have it) to cut out the holes, I would suggest cutting the hole slightly smaller than the inside of the circle you’ve marked for the switches. This way it will fit snug in the hole and it will not slide out easily. You can always remove a little more foam if you’ve not cut out enough.
After confirming the switch fits securely in the newly cut holes, it is time to make the hole in the leather. Once you have the leather pulled back over the foam, you should be able to rub your finger over the hole for the switch. This should allow you to see an outline of the area. I found by taking a black sharpie and placing a dot in the center of the hole to use as a guide, I know where to begin to cut through the leather for the seat.
Once you have selected the best location for the seat switches, we will now need to drill a hole for each switch. I first used a 3/8” drill bit for a small pilot hole. The purpose of this hole is to route the wires through the foam to feed the switch, and through the metal or plastic seat pan. After the pilot hole has been drilled you now need to drill the actual hole for the switch, you will need a 13/16” drill bit. Prior to drilling the 13/16” hole, you need to make sure to have a small gap between the two switches. It is recommended there be at least ½” between the final cut outs. Unless you follow this suggestion, the two holes will be one large opening and will not allow the switches to have a secure mount..
Once you have the hole(s) cut, it’s time to install the switches and hook up the wires. Just make sure to follow the wiring diagram provided by the manufacturer. As well I have provided a wiring diagram in Step 10 for your reference.
For added protection, I would suggest an inline fuse for the + positive (red) side of the battery. Place a ring terminal end on the side of your inline fuse that will be mounted to the positive post of the battery. For the other end of the inline fuse I would suggest a butt splice, or solder and heat shrink the ends together .
Next on the black negative wire, place another ring terminal end on one side, and a butt splice on the other, that will connect to the black wire on your wire harness. Once you have both wires completed, connect them to the motorcycle’s battery. Make sure you do not have the harness connected to the motorcycle seat at this time.
*Now that the wire harness is connected to the battery, this would be a great opportunity to verify that all other connections for the seat are working properly. Place the seat on your motorcycle, and plug it into the harness and test to make sure that both switches are turning the Heat Demons on and off.
Once you know the heater(s) are working, remove the seat from the motorcycle. And turn it over and while keeping the leather pulled tight, using a staple gun install the staples to your seat.
Now that you have installed all of the staples back into the seat, take the seat back to your motorcycle, hook up the harness from the seat to the battery, and mount the seat normally to your motorcycle. Test one last time to verify that both switches and Heat Demons are working properly.
