Temp Gauge Wiring

["Gregory Groiss" <ggroiss@gmail.com>]

Hello All,

On the back of the electric temp gauge there are two terminals.  One
goes to the sending unit in the head and the other goes to ???? Is it
a ground?  Also, neither post is marked what wire goes to what post? I
am switching from the manual temp gauge so I have no reference point.

Thanks,
