Headlight buzzer operation

The other day when I had my dashpad off I found that I have a buzzer that someone unhooked. It's above the glove box and it works when I leave the key in the ignition and open the door. (I kinda wish it wouldnt do that, I leave the key in it on purpose a lot) It does not work when I open the door with the lights on. It has power at the buzzer on the brown wire. Is it supposed to buzz when I forget to turn the lights off?

On the 80-82 trucks, the headlight on buzzer is a separate buzzer from the ignition on buzzer. In 1983 they became one buzzer. I'm not sure if there were two different buzzers for the 83+ trucks, one having the headlight buzzer stuff and one without. It could be a difference in the wiring too. 81 Explorer can explain the 83-86 trucks a little better than I can.

I'm just wondering why it would have a brown wire going to it from the park light circuit if it isn't supposed to work that way, I'm way more woried about forgetting to turn off my lights than leaving the key in the ignition.

I thought about rewiring it to make the headlights turn off with the ignition switch, I have headlight relays so it shouldnt be too much load on the ignition switch. I'm not sure why they don't do that from the factory anyway.

On my 1981 F100 XLT it has the light group option and it has two different buzzers for
the key in the ignition and the headlights on.

1984 was the first year they were combined into one buzzer, and the factory wiring goes all the way to the buzzer for the headlamp reminder.

However, they had two different types of buzzers that plugged into the 1984-1986. One with headlamp on buzzer connection, and one without they put into the base and XL models standard.

What bashby needs to do is find a buzzer that has the headlamp on buzzer connection and plug it in. That's all he needs to do to get that to work for him.

People that have 1980-1983 trucks needs the whole lightgroup underdash harness to plug into the main harness. This includes the buzzer, both underdash lamps, ash tray lamp, headlamp on buzzer connection, and glove box lamp conections.

1980-1982 light group harness is interchangeable, and found on broncos too.

1983 is a one year wonder and only the 1983 light group harness will work.

1984-1986 it's already prewired for the headlamp on buzzer.
