Easy to install - as mentioned, take off the 6 screws at the top that allow the electronic board to drop down. The switch box itself is really hard to squeeze with fingers alone, but basically grab a tightening wrench or something that can pinch the clip on top and bottom, and free it from the head. You can do this before (or after) removing the 4 wires - i removed the wires first. You'll have to really wiggle them for them to come loose - hard to get off, easy to get on. REMEMBER to label them or take a pic so you know which one goes where. Then simply push the new switch in from the outside of the unit (requires some force to compress those clips again), and reconnect the inside wires, ensuring there's no bare metal showing on the connection (there should be plastic sheathing to slide over the wire ends). Done, less than 5 mins.
