I haven't looked at the wiring diagram yet and I will, but the horn on my 68 has a 2 prong connection. My challenger has a single, so the horns operate differently but look similar. I was trying to figure out if there is a direct connect aftermarket horn or something that anyone has used. Just trying to get some ideas without hacking the wiring.

Is one of the connections on the 68 for a ground? If so, you could simply use two short jumpers from your connector to the horn and ground....and use a single prong horn.

Horns are pretty universal and interchangeable. As mentioned they will either
be 2 prong, a power and ground or 1 prong for power and ground through the
body. The 69-71 (and probably all Swepts?) work with power always supplied
and the horn button supplies a ground. Easy enough with 2 prongs. If using
a single prong, then the switch needs to supply the ground to a relay and
then the relay can power the horn. Looking through my manuals, it looks like
not all Swepts used horn relays. I have no idea what the deciding factor was.

I pulled a dual tone horn from a Lincoln (I think) at the salvage yard, hoping
to find something with a deep tone. I remember my Grandma had an Olds
with a horn like a freight train! Turned out the high tone was dead and the
low tone sounded just like every other horn. Oh well.

Cheap replacements are easy to find at the parts store, or you can hit the yard.
I am going to see if the yard will let me bring in my jump box for my next horn
hunting adventure.

I also got an air horn I plan to wire up to the truck in the near future, just
haven't found the perfect place to mount it yet. I am thinking of wiring it
so the normal horn sounds with the key off and the air horn is active with
the key on. This should cut down on the kids playing around in the driveway
while I am under the hood! Pretty simple with a single pole, double throw relay.

Hola All

I have a 1978 D150 that came with one horn
mounted on the battery side. Then one day
while at the pick & pull I saw a like truck with
a second horn mounted on the passenger side
of the radiator. My second horn, the mounting
bolt and the wiring cost me $3 .

On sweptys with two horns,there is a relay.There is no relay if just one horn.

The horns were one part of my crew I could tell had been jacked with previously.
One horn with a relay, but it was all kind of loose and flopping around.

Good to know.

Thanks guys, I'll have a look around. Mine is so queit I haven to scream out the window as my horn.

Nfury8, I couldnt help but laugh when thinking of that horn going off in your face.... I had to.

I put an air horn on my truck. It was really high pitched and super loud. dual tone, I loved it. The switch wired straight up to the compressor, now that I think about it I probably should have used a relay. Anyway, my truck sat around for about 2 years and the compressor died in that time. The air horns are still there, just in front of the radiator, but nothing to power them.

Ok, i thought Id bring this back up a change the title. I need to find a working horn. Not too interested in running an air compressor and all but I need a good cheap horn that you can hear.

I thought I figured out the problem, my old black steering wheel had the jumper wire down to one little strand but then I put my white wheel in with its original jumper (intact) and now it doesn't work at all.

I will try a brand new wire but I also think i still need a horn.

Dude I've got a horn if you need.

I am down, it works ok?

Let me know how much. I've been going crasy buying parts lately. I love it.

Easy solution to the horn problem..

Install a train air horn!

You can get single, double, or triple-trumpet horns; that on a pickup, would install under the truck (bed or cab), or on top of the cab! And they are
LOUD!
Try anywhere from 110 to 156 dB loud!

A real crowd pleaser, and people WILL hear you loud and clear. Your vehicle is no longer invisible to John Q. Dumba$$ in their Prius or their Lexus, chatting away on their cell and sipping their latte!

I plan on getting a 120 dB version for my truck in the near future. It's amazing how invisible my 1-ton Cummins Dodge is to these dolts on the roads!

Patrick, where would I find one? I have wanted a train horn for years, just didn't figure the general public could get them.

Yes they are LOUD. I'll probably be able to hear yours from my house.

Thanks

That would be cool!!

Sounds like Doug has you covered, the parts stores will all have decent, cheap, loud
aftermarket replacements. Although they are all DOT spec stuff, which I think is too
high pitched.

On the topic of air horns, real train horns can run 1 to 2 grand!
Wolo http://www.wolo-mfg.com makes a wide range of aftermarket electric, air
and train horns for about any budget. They have sound samples for most online.

I have their 418 Powerhouse horn in the garage for my Crew, picked it up at Harbor Freight
for half what their website lists. Their 846 The Chief is the one I would really like, sounds like
a fire truck horn! It is over 2 feet long though.

Dougs got me, Im going stock for now.

i pulled a pair out of a late 70's eldorado....buick riviera is the same.....those dudes are loud !!!!
