Installation Overview

Please read these instructions, completely, before starting.

The installation is done mostly from the side of the bike with the seat and side covers off.

Items you may need are something that resemble the following:
  • Straight edge screwdriver
  • Phillips screwdriver
  • Regular pliers
  • Needle nose pliers
  • Large file
  • 10" long adjustable wrench
  • long thin narrow kitchen knife
  • long flat piece of bendable metal (9"x1"x1/8") with no sharp edges
  • a Dremel tool or something that will cut the base of the seat
  • a 4" block of dense foam rubber, a 10-12" square, clean shop rag or old washcloth will do
  • a large towel or blanket

Please note that the basic instructions are for a seat with an existing 1-1/4"x3-1/2" hole in the bottom. For seats without an existing hole, please refer to, modifying your seat, for help before continuing with installation.

When referring to the left, right, top, bottom, front, back or side, it is in relation to the seat being on the bike in riding position.

Placement of the device is preferably located at dead center where you sit on the seat. It is most noticeable and comfortable in this location. Installing the device too far forward may cause the unit to operate less effectively, as a result.

Remove the seat and place it upside down on the towel or blanket to protect it while working on it. If your seat has a large enough hole already, the only concern will be the ability to maneuver the device to it's desired location in the seat. You may have to modify an existing hole in size or location, or you may have to make a specific hole for the insertion of the device. Refer to (Fig. 1 & 2) which show a typical seat. Using the large screwdriver or long knife, CAREFULLY make a long slit in the foam where the device will go. There are thin strings embedded in the foam of some seats that will have to be cut while making the slit. Very carefully, deepen the slit towards the top of the seat. Keep your hand on the top of the seat the entire time so you can feel what you are doing on the other side. Do not go too deep! YOU MUST leave at least 1/2" thickness of uncut foam on the underside of the seat but no more than 1". You do not want the device directly up against the seat covering. It will make a lump and be uncomfortable. The deeper you cut, the closer the device is to you, the more noticeable it becomes, and you increase the risk of feeling a lump in the seat. The best way to describe the installation is that you want to get the device laying horizontally, perfectly centered front to back, side to side, and top to bottom, embedded in the foam. It is advisable to start shallow and cut deeper into the foam evenly, as an adjustment to obtain the desired thickness of foam left uncut. If you have to make an adjustment that requires removal of the device, do not pull the wire while removing it. You WILL damage it. Once the slit is made, use the handle of the adjustable wrench to go in from the hole to pry the foam apart gently to make sure there is enough room for the device. Once again, keep your hand on the front side of the seat. I chose this tool because of it's rounded handle end and knowing it would not bend under pressure, cut the foam, or damage the seat. Do not squeeze or force the device in, doing that will damage it. Insert the device, flat end first, sideways through the hole, with extreme care not to damage the wire pointing out the rear. You must keep the foam pushed away from the base while doing this. At no time should you push on, squeeze, or pry against the device. Your fingers should be used to move and position the device and the adjustable wrench handle to keep the foam away from the base allowing you room inside the seat for positioning. Keep at it until the device is completely in where it belongs. The wire exits the device on an angle, and should be pointing down and back at all times to avoid damage to it. (Towards you, out the hole.) Once the device is in the seat, you will need to insert a lifting pad below it. The reason for this is, if you make a slit and push the device up into it, there must be something under it to hold it "up" in the slit or it will drop back down against the seat base rendering it less effective and useless. A folded shop rag, washcloth, or chunk of dense foam rubber will work nicely. You can substitute whatever you like, as long as it resembles the "feel" of the seat padding and keeps the device securely "up" where it belongs. Folding the shop rag or what ever you use, and inserting it through the access hole so that it becomes centered below the device and provides padding between the device and the seat base is the next step. Make sure you do not get snagged on the device while inserting the padding. The tool I chose for this was a thin wrench that had a bend in it which enabled me to "tuck" the padding in quite easily. A flat piece of bent aluminum stock will also work well, as long as there are no sharp edges to damage what you are inserting. The wire should exit through the access hole and gently loop around towards the right side. Use the enclosed zip tie to hold the wire secure to the underneath of the seat. You can drill a small hole next to the main hole and attach to the plastic between them. O.K. relax, the hard part is over.

Put the seat aside.
