I'm about to run wiring and I have an electric fan thermostat and temp gauge sensor. Instructions for fan temp sensor say to install in head or inaccurate reading may occur. The location I thought I'd use is left front, top of intake manifold. Since I'm not running a heater I thought I could use the opening behind thermostat for the gauge sensor. Any suggestions, or issues with these locations? Pics appreciated as well. Thx, Don.
