Ok, I did the web research and cannot find a thing.

I am running SPAL fans in my 55 Wagon. The ground goes to the temp sender and it also has a ground toggle in a supplemental switch panel under the dash. Flip the toggle and bypass the sender and the fan starts right up. Pretty basic ground side toggle right?

So I want to run an indicator light to show the fan is on, so I bought some indicator lights from Ron Francis. Here's my question. Since the power is direct to the fan, can I run an alternate power lead to the indicator light at one side and wire the ground to the toggle? So the fan and indicator light are hot on one side from different sources and when I hit the toggle the fan comes on and the indicator lights up.

Two power sources and one toggle at the ground to complete the circuit.

This should not be an issue right? I am having a brain cramp.

Thanks for the help boys and girls!
