I have one on my '01 220. It works great. It should have come with explicit instructions. If not, you wanna hear it, here it goes; first mount the magnet in one of the f. rotor's free floating holes w/ epoxy. For the pick-up sensor you'll have to check the proximity of the magnet and sensor (magnet too high you'll get a double hit, too low it won't pick up). Next drill a 1/8(3.25mm) hole in the caliper for the mounting screw (don't worry, non-working part of the caliper). Mount the sensor,and route the cable along the brake line. If you still have the stock brake guides, you'll have to cut them and super glue them back together for routing. Now if you have the Super Trick Billet Mount, you need the loosen the handle bar mounting bolts, install the mount then re-torque the bolts back. Install your comp and start loading wheel size. :aj:
If you don't have the Super Trick Billet Mount :whiner: I am sorry I can't help you. Just kidding! :) Install the stock mount on the bar, hook up the cable, and mount the comp and that's it. WHEW! No....wait, then load your wheel size then that's it. DOUBLE WHEW !!
Have fun and enjoy.
