No, not after market. It is the "New" light switch that the military bought. There are some smart people here who can tell you how it is SUPPOSED to work. Simp for one will know. Many others. I hated the darn things and liked the old three handled ones. If you look at the wire diagram, you can use a wire to test lights, at the plug. I THINK, but haven't looked in 10 years, but think pin A is power. You can jump from power to each circuit and get lights to com on, one at a time. I am sure the test procedure for the switch is in the books.
