horn?

[1990LTD]

I don't know if this belongs in this forum or another, but, could I rig a second horn? I've got the button on either side of my steering wheel for the horn and there are two under ye olde hood, so...could I tear one of them out and get an old timey "AH OOOH GAH" horn and use one of the buttons for that and one for my regular horn?

Horns are pretty easy to wire up. I'd suggest using a relay though, as they draw quite a bit of current when they are in use. Even so it's pretty easy.

I understand that there are two outputs, if you will, behind the horn pad but i dont know it they can be used individually of each other or not. I guess you could try it, but like GoodSamaritan said use a relay to power it.

I don't think there are two separate contacts on the slip ring for the two different horn buttons - I think they combine and then go into the slip ring in the steering column as a single contact. Can anyone confirm/deny? It's been quite some time since I had mine apart.

On mine it seems to connect up as one piece right at the actual wheel. I was thinking along these lines recently, but I think you'd need to take one of 3 basic routes:

1. have the new horn entirely separately activated. New wiring and a button or pullstring or whatever somewhere in the cabin

2. mount the new horn (in series?) to go off along with the current horn. If it's louder, it'll be the main thing you hear. This probably wouldn't work with the oohgah horn.

3. Do a direct swap of the current horns with the new one(s) and have it still run through the steering wheel.

I doubt either horn will sound right in if you wire it in series. Series would mean that the ground wire of one horn went to the hot wire of the other horn, and then that horn in turn was grounded to the frame.

If you wire the horns together, wire in parallel, (meaning one hot wire splits into two hot wires which go to each horn, then both horns are grounded) but put a relay on the non-stock horn so you don't blow fuses.

Do you have cruise? Does it work?

I'm not sure how many wires come from the cruise control buttons, but you could have as many as five different horns triggered that way. It all depends on how FOMOCO configured them.
Of course it goes without saying that you would absolutely have to everything through relays to make it work.

Now I have visions of a box with the whole grille filled with different horns. You could make your car sound like a one vehicle traffic jam.

Will a pre-'85 multifunction switch bolt up to your column? If so, that could be one convenient way to actuate a second horn.

BTW, factory horns used relays at least by '87. I discovered this while investigating why some juryrigged horn wiring left my horns all quiet and tinny-sounding.

I have 4 horns wired in parallel, the resulting tone is way off-key and very annoying, but very noticeable.

You could wire a SPDT toggle switch and relay to change from normal to ahooga horns using the horn pad button to activate both individually.

Do you have cruise? Does it work?

yep and yep

I actually kind of hate the stock horn, so could I just replace it with the other?

[1987cp]

No, it's physically impossible to disconnect the stock horns.






j/k Actually, that'd probably be your very easiest approach if you want louder aftermarket horns on the car.

thought so. thanks bro

Cool I have stock horns, oogah horn, and a set of air horns in the cruiser, and a oogah horn in the party van

[1990LTD]

What work is involved in replacing the stock horn?
