Make that "breaking off a plastic tab"

described recently

The center and one of the side wires have to be swapped.  Forget which 2,
did it a couple of years ago by looking at a bulb, guessing and testing.
It was relatively easy to figure out, harder on the fingers to get the tiny
plugs out of the sockets.
