Here is where I tapped into my cooling system to install the switch. I should have tapped into the t-stat housing because the cooled water, that leaves the radiator, never reaches a high enough temp to ground the switch at 195 degrees. I will change this later.

So, tap into your t-stat housing on the top above the thermostat. There is a flat spot with a "plug" there that will work just fine.
