[DeTomaso] indicator light

[Dave McManus]

Chris, 
Wouldn't your lights indicate you have 12 volts to the fan motor and the
fans might not actually be turning (fan motor failure, burned up motor,
broken internal wire)?

What I did was to tap into the wires at each fan motor (I have three--much
to Mad Dawg's chagrin!) using the positive and negative leads right before
they went into the fan motors and ran the thee pairs of wire to the dash.  I
drilled three little holes above the headlight switch and mounted three
different colored LEDs (which I bought at Radio Shack--made especially for
12 volts) so now I know exactly when each fan is operating.

The LEDs must be hooked up correctly with the positive side to the positive
wire and negative to negative.
