Water temp wire on 06 OBV

Anyone know where the water temp wire is under the dash on an 06 OBV? I don't have a water temp gauge but there is supposedly a wire up to the dash that you can tap into.

OK, I think I found it. There's a two wire white plug that has a tag on it with "paddle wheel hrn" typed in dot matrix font. It's currently not attached to anything, but just comes out of the wiring harness that goes to the back of the boat. Any thoughts?
