Do NOT hook up power to the center terminals!!! Power for the switch is provided by the BCM. It is a "sinking" input - that terminal on the BCM is hot until you press the button and then it is sunk to ground potential.

I'm not sure about the light. I didn't see anything in the FSM whilst looking up the other info (doesn't mean it's not there, just that I didn't see it). What I would try is activating the switch and taking some readings with a voltage meter. One of the outside terminals should have 12V when the flashers are on (may be pulsing) and the other outside terminal will probably go to ground.
