Can anyone confirm that thw MB buzzer is for the oil pressure, or is it in case you leave the radio or parking lights on when you open the door?
Thanks!
(I think the later relays can be used in an MB, but I'm curious about the buzzer as the old relay does not have a specific output for it, while it seems the newer ones do.
I could add a buzzer in to the circuit if it doesn't already have one!
