i think i remember Bucci had a buzzer hooked up to his EGT gauge. i was looking at apexi website and came across their PDF manual.

on page 4 it says that the orange wire is for "warning output signal (for realy)"

does that mean i could hook up an external warning light or buzzer by using a relay?
any help would be greatly appreciated
