Just installed today. It works as advertised, although the shiny instruction card has no value. I didn't wire what the instructions say. A few minutes with the meter, and a few more minutes with the switch connected to the battery, I could tell that the red and black (positive and negative, respectively) wires turned on the switch's LED. I wanted mine to be normally open and have the switch indicator on when the switch has power. Red to plus, black to minus and two blue wires between plus and my load. The two yellow wires in the blue connector are not required. I assume they are for normally closed applications. If the blue connector is removed from the switch, you will see a small rectangular slot for each wire pin. By firmly inserting a small jeweler's screwdriver, it was possible to extract the pin, and with it the yellow wires, from the connector into this small rectangle. The appearance of the Revain looked beautiful. Looks just as good after installation. Added bonus; I quote "[3 YEAR WARRANTY, GET A NEW ONE UNLESS MAN-MADE BROKEN]" SMH!
