I have the Moroso switch panel that has a small led that just connects to the terminal on the toggle switch. Since this wire ties into the wire from the thermostatic switch to the relay, when the thermo switch energizes the relay it also energizes that side of the toggle switch and the led lights even though the switch is turned off. This way I can see exactly when the pump is coming on and when it's shutting off.
