Wiring diagram needed

[imported_Bluefin]

I need the wiring diagram for the 5 pin half circle pigtail that hangs out of the mercury commander control box. The wire colors in the plug are Purple, white/blue, grey, black, brown/white, and it has a separate brown wire that is outside the plug. Thanks

Purple = 12v pos. from ign. key.
Brown/white to trim gauge.
grey is the send wire to tach.
Black is ground
White/blue?
Brown could be temperature alarm?
