I didn't remove mine. Just remove the nut cover, take nut off, remove washer, then pull the pedal assembly up and to you, unplug the only plug. Plug SB inline then put it back in place, starting with the top of the pedal. All the instructions say use a magnet to remove the washer, but mine couldn't come out with a magnet, so i had to use some super glue on the end of my socket, put it over the nut and onto the washer, then pull the socket back out.
