Afternoon all,

So, what the heck is this? This was plugged in to the fuse box on my 75 coupe. I searched the part number and got nothing. I searched the Patent number and found reference to a buzzer. Is this the door ajar buzzer?, and if so, any issue with leaving it out?

Thanks,
Bryan

are you able to make it buzz? Is that a button on the front?
Do you have a 1975 build manual?

No power to the car at the moment so, no, can't make it buzz. That is not a button. Looks like it though.

My 75 has one exactly like that, i also have no idea where it came from.
It may be the headlight buzzer as Mooser said, but its sitting on the shelf for the last 20 some odd years.

Well, that explains why my car does not have it. All annoying screeching PITA buzzers have been pulled and tossed into the rubbish where they belong.

I know this is an old thread, and Im not supposed to reply to old threads but I have been looking high and low for this buzzer and wiring discussed in this thread.
If anyone still is listening and has one of these laying in a box, I would be very grateful to be able to buy it from you.

@Rescue Rogers @mooser @BEJ @Mod75 @wer2xu

Thank you!
