Folks,
I just bought a Bennington and want to wire my Humminbird Helix into one of the open acc rocker switches. The switch has power but is not connected to anything on the boat. Below is a picture of the wiring. Do I tie into the blue with the red from the hummingbird and the black with the black? It seems the orange goes to the breaker and the brown I have no idea. Any help would be appreciated!!!

Pin 3 should be your output on most of these switches.

I believe the orange wire is the feed from the circuit breaker, the blue is the 12v after switch, brown is for the light in the switch, black is ground for the light in the switch. Check it with a voltmeter to be sure, trace the blue wire if not used it will end with a plug.
