ATV Thumb Warmer Installation
1. Peel the release paper from the thumb warmer and adhere it to the
throttle, facing the rider.
2. Slide the heat shrink tubing over the thumb warmer and
throttle. Use a heat gun to shrink the tubing. Be careful not to
burn it.
3. Use one cable tie to secure the wires to the throttle. If using
additional cable ties to secure the wires to the handlebar, be sure
to provide a strain relief so the throttle does not strain the wires
when in the full open position.
