Tacho Wiring
The AEC 104 B-660 / B-780 features two tacho output lines.
Terminal 4 supplies the standard AEC tacho signal, which is also
present if the preset rev limit is reached. Terminal 4 is wired to
the tacho in the Lamborghini Countach.
Terminal 5 supplies a tacho signal which drops to zero as long
as the preset rev limit is reached, leading to a slight bouncing of
the tacho needle while at the rev limit. Tacho's on fuel injected
Ferraris are connected to this terminal.
