Take off back cover. remove all screws, take a picture of the switch to make sure you have the correct wires going to the proper terminals. Remove old switch and install new one in reverse order. While I was in there I replace the worn F/R Change Lever. Also replace missing bumper and cracked hammer case cover, they just snap on.
