Hello! I'm new here so be easy on the old guy! I have a 69 Dart GTS 340-4sp, non ac. I can't seem to figure out what this is for. It's located on the bottom of the dash below the glove box. Thanks in advance for your help. Thanks FABO

Headlight warning buzzer for sure!

Although it does not look quite like the original one. It appears to have been opened up before. As well.

key off, headlights on and open a door, it will buzz to remind you to shut the lights off.


Original.

Yellow with black trace come from either door switch, double poll style. Black is +12v Hot from the headlight switch with lights on, black/white trace is ignition on +12V hot from the #3 accessory fuse used for this and tach if equipped.

Unplug it and see what quits working. lol
 
well, that's the problem. It was unhooked. The black wire has gotten awful hot & started melting. Not sure if it is the correct one

The connector is wired correctly!

likely a bad buzzer!
 
Available on E-bay and very steeply priced.

keep an eye out as they pop up for around $30 often enough.

leave it unhooked for sure! Burnt wires are bad news!!!!
 
What I have in my 67 is something like this but homemade (piezo buzzer and a couple of diodes under heat shrink). Not much larger than the lollipop they give you at the bank. its high pitched beep isn't loud but right there at the fuse box so I do hear it. I built about 25 of them before I knew aftermarket offered something similar.

You could completely amputate that antique buzzard and its wiring. That black hot wire may not be fused. I don't have 69 wiring diagrams to confirm.
This replacement is attached at fused/line out side of 2 circuits at the fuse box.
One difference is it activates at ignition switch off if lights still on. The door jamb switches are not related.
 
The black from headlight switch term R is not fused separately as it is parallel with the running lights, IE tail and front park. The black trace is fused as it comes straight off the fuse block.


The whole unit Is really simple in design. The black/trace +12v energizes an internal relay via case ground to bypass the buzzer when the key is in run position. When the key is off the SPST relay de-energizes and allows the +12v from the black term R headlight switch to one side of the buzzer. Ground path to the buzzer is achieved when either door switch grounds and or door opens.

By the way that is likely 74-77 horn relay. As you can imagine this Is why you are back feeding power to who’s knows and wire burn! Is it a 3843233 relay by chance?

No. Actual part # was on the back of the relay. Pt # is 2983330 93596-A. Also a # 2428 on it
 
Some unknowing person plugged this into my harness prior to 1984 thinking it was the same. It burnt up wiring as you say. As picked left top is term is +12v Fused and the middle lower is ground from the horn ring and right upper is +12v out to the horn(s). Kinda looks the same but not!! It is a 3843233

Working on it. Your wiring harness is correct though. I assume your car has an A-01 option.
