[oletrucks] GMC type temp gauge

[MASK4335@aol.com]

I'm replacing my some of my Chevy gauges with GMC replacements, oil (0-60 for
my 235 engine) and temperature (electrical instead of closed tube type).  I
need to know how to wire this type temp gauge in my upgraded 12 volt system.
Must I use a resistor and if so, what size and where?  Has anyone else done
this modification to their trucks?
