This Dummy Needs a Headlight Buzzer

[Gasasaur]

Does an '87 Silverado have a warning buzzer for leaving the headlights on? If it has one, it doesn't work. And after this weekend............I think I need it.

[68Timber]

Napa carries them.

Oem?

[Gasasaur]

I guess my point was missed. I didn't know if the truck was supposed to have a warning or not. Evidently it is and mine doesn't function. Good to know it did originally come with one and I can get it locally. Thanks.

[68Timber]

No sorry, they never had headlight buzzers, not that I'm aware of anyway. Napa has an aftermarket buzzer for a few bucks, I've installed them on both my squares.

[LDO]

I have actually been looking into this. I believe the Silverado models (I have an 85) came wired for all the buzzers (headlights, key & seatbelts). The difference is in the buzzer module itself. You have to pull it and see if you have a 7 pin module or not. The 7 pin is the one that will buzz for key, belts AND lights. The other one (the one I have) has 4 pins and will only buzz for key and belts.

It is located over by the gas pedal.

I plan to go to a junk yard and look for a 7 pin one.

There are several GM PNs to look for:
22535998
22533568
are just two of them. These modules were used in other GM vehicles as well.

There are a few on EBAY but they want too much for them when I can pay a buck to get into the yard and the fella behind the counter will prolly just give it to me or ask for 3 bux.

None of the parts sites I've found carry them anymore.

Now you know everything I know about this.

[Gasasaur]

Well LDO, I don't know if you've done anything else worthwhile with your life, but if nothing else, you are a SBCBG (square body courtesy buzzer guru) in my book.

I wish that would get you a cup of coffee, but I'm afraid it's not in the cards

Thanks for the great help.

UPDATE:
I was wrong about the pin count. My old one is a 6 pin, the one I (we) need is a 7 pin.

Here are pics.

1st pic is my stock 6 pin that has no headlight tone.
2nd pic is a 7 pin unit out of a 97 Silverado.

As soon as I popped it in and turned on my headlights, I got tone!

I had a 79 Malibu that had one, I'd think it be an option in the 80s....

LDO, that right there is an awesome tip! Nothing like being stuck with a dead battery at Wally World of all places. Not speaking of myself of course....

I believe I will look into this as well for my 82. I get comfortable with my newer vehicles doing things for me that I am prone to leave the lights on as well . Good info LDO .

I used the wiring harness from a 1989 Suburban when I re-wired my truck. It has a buzzer that comes on when the key is off and the headlights are on. I will have to see if I can find a part number.

[LDO]

Sorry for hijacking your thread Gass but it was such a coincidence that I was working on this myself and none of the older threads really helped much so I couldn't resist.

It seems alot of the earlier 80s trucks could have been wired for it but you will have to check. When you remove the module, you can tell if you have a 'female' receptacle for that 7th pin and that will tell you if you are wired. For my 85 Silverado, it was. I suppose it wouldn't take too much to wire it and make it look stock if you had a wiring diagram.

Best of luck to all. I'm hitting the junkyard this weekend and will try to scoop up as many of these units as I can and plan to send some out. When I was younger, I would prolly have pulled these out and trashed them, now that I am older (wiser?) I want the buzzer! LOL

[Gasasaur]

Sweet, I just checked and while I have the 6 pin module, I can see that there are 7 pins wired in the receptacle. I know what's on my "to do" list!

Just for reference, it's an '87 Silverado.

Hey, I just thought of something. I brought home a 1990 S10 the other day so I can make a bed for my grandson using the bed from the truck. I'm even going to slice the last few inches off the cab and use it for the headboard. Anyway, I wonder if it has a 7 pin buzzer in it that would fit my Silverado? I'll find out today when I get home!

[LDO]

Cool,
it might! If not, I have a feeling I will have a few after Saturday.

You did good Robert!! I just might have to look into this myself, I'll hit you up, when I need one!!

Yeah, we were just talking about it the other day so I figured I would dig deeper.

[Jay2Cor517]

I was just thinking about this the other day--this is great. Someone answered the great mystery. LOL. By the way, should this be added to Your Favorite Budget Mods ($50)?

[N2TRUX]

This is a great thread. I asked about this quite some time ago and everyone questioned why? When your daily drivers have had auto cut off for many years, turning the lights off and on is no longer instinctive. If your like me and love the look of park lights at dusk, its easy to leave them on.

Does anyone know what year they added the socket to our trucks? Where exactly is this socket?

[LDO]

over by the gas pedal. it's a panel with a flasher looking thing, this module and another larger module which may be the cruise control.

I can take a pic when i get home tonight unless someone else beats me to it.

I'll second that!

[LDO]

So I take my son to the junkyard and show him what we are after today and what possible year trucks would have it. Explain to him how to remove it and hand him a common screw driver. 10 minutes later, this happens. The kid was running around the yard like he was on an Easter egg hunt!

Here is the pic of our stash.

LINKY FOR ONE

[Nessmuk]

I use a relay in the two power feeds, switched with an orange, ignition hot wire, or tap into a free spot in the fuse box.
If you look up how, it's not bad getting the wire out of the light switch plug, and then get another light switch harness to get a length of each wire to run from the relay to your OEM plug, it is reversible. If you ever need your lights with your engine off, turn your key to acc.

I need one of these also, Hoping there are a few 88-91 suburbans in the wrecker
