I wrap the sensor wire around the brake cable until it reaches the metal noodle ( curved cable end). Then the cable is run down the outside of the right fork tube to the best location to mount the sensor. Make sure that there is plenty of slack in the sensor wire and loops around the brake cable. Wires pulled tight usually = damaged or broken wires. Apply tie straps as needed to prevent the sensor wire from snagging on anything and test ride the bike. When you are satisfied, cut off the excess tie strap material.
