It's the circuit that decides when to blink the LED, and does the blinking.

 From the old-type level-controller should be no problem -- if you
want it to blink you can get an LED that blinks internally.  The
newer short type would need a bit of extra circuitry most likely.  We
can pmail about it.

Aftermarket gauges ought to be set up either to run unregulated or
provide their own internal voltage regulation.  I see no advantage to
trying this hookup.

I don't think you're tied to the WBX gauge if you don't want to
be.  We can pmail about it.
