Four note Horn

[gman]

I have a 98 eldo and I want the classic 4-note horn. Anyone know where I can find one? Is the horn from another model, Deville, interchangeable with mine? Thanks.

Any GM OEM horn(s) will work with your relay. Mounts may vary.

Hello...

Here are the OEM horns:
F-note #D1922C (see #12368064) low
A-note #D1925C (see #12368063) high
Horn relay #15-8571(see#12088567)


Here's what I bought to accompany the horns already in my 2000 Seville

D-note #D1923C
C-note #D1925C (high C)

I'll probably work on these horns this week.

Post back any details if you decide to install.

Sorry to dig up an old thread, but PMing is disabled until I get 50 posts.

Just wondering how this came out for you Eldawgg, I'm attempting this in my 99 seville tomorrow, I stole the D and C note horns off of my buick and plan on installing them in the cadillac.

Hello...

Turns out the donor horns are bad and I haven't been to the boneyard to pick up another set yet.
I have posted horn diagrams in another thread.

I had almost forgotten about doing this...thanks for the reminder!
Post back your solution.

Well I couldnt make it work. The horns themselves must be different in some way. First I wired one new horn into an existing one, giving a three horn setup. I tested the horn and I heard the relay click, but no horn. Checked the fuse panel and it cooked the 15A fuse. So I put a 20A in, thinking, okay, more horn, that added a resistor, and its a parallel circuit, so the amps have to be stepped up to compensate. I tried a 20A fuse, and it cooked that too, then a 25A fuse. Fuses arent exactly the cheapestthings around, so I disconnected my added horn and it worked again with a fresh 15A fuse.

Rather than figure out this headache I'll drop 25 and get a train horn from JC whitney. THe horn isn't bad in the caddy, but when your used to sounding like a train, you miss it
