Seeking a float switch source for low coolant circuits

Thanks very much, Art. I appreciate you taking the time to walk me through this. Do I need to be concerned with what gauge wire I use to power the relay coil?

The diagram on the relay would indicate that 86 is a 12V feed and 85 is the ground. When I put a meter to it on the bench I have continuity 30 to 87A.

Does this make sense? When power is supplied to 86 (in my case the closed float switch) the coil will open that 30 to 87A path and the dash lamp will not illuminate. If the float switch falls enough to open the float switch the relay coil will lose power causing the dash light to illuminate.



Edit: This is not compatible with Dave's wiring suggestions. I am confused I thought the coil power had to be interrupted to cause the dash lamp to illuminate.
