Re: DIY Horn Upgrade Mod

Sun May 22, 2011 9:03 am

I still like the horn pair I used when I did my upgrade. Doesn't need an extra relay, is easy to install, and has a great, commanding sound. Some have used the 400/500 Hz. version instead, liking the deeper sound...

Maybe we can get a volunteer to have their car converted from below when the SF BayLEAFs meet at Luscious Garage on June 4th? I'm game if I can figure out a charging strategy for getting home (53 miles one way).

I did this today. I bought these for $20 from Checkers:
http://www.oreillyauto.com/site/c/detai ... &ppt=C0107

My horns each had their own power and ground male faston connections. It also came with short jumpers that you could ground one terminal to the mounting screw. I used those but I also wanted to connect the OEM ground... so I remove the Faston tab from the OEM horn's ground and put it on the bracket of one of the horns which allowed me to connect the OEM ground to the horn's bracket. I had to drill out the hole in the tab slightly.

I did go in from the top ( I was lazy and didn't want to go under the car), but I didn't remove the reservoir. I unbolted it and flipped it to on top of the radiator support. No need to remove the hoses.

I bolted the two horn brackets directly to the main bolt, not to the OEM horn bracket. i.e. I removed the OEM horn and bracket. I felt the bracket(s) would be flapping in the wind too much. Though I'll say the brackets in the OP's pictures look much better than the ones that came with my kit. That still doesn't change the fact that the OEM horn bracket is pretty flimsy.

The most interesting thing to me was that the horn is NOT used for the noise that gets made when you press the keyfob lock button. I was expecting the noise to change but apparently there's yet another horn somewhere that makes the muted sneeze sound.

Yeah, the alarm has its own horn which is up in one of the fender wells. The logic is that its placement is to thwart someone from disabling the alarm.

It is interesting that the Fiamm and the Wolo horns look almost identical.

Looking forward to putting that on the car in the morning.

I assume you bought the louder and better auto model not the compact moto version which is not the same output and tone? This horn will require the addition of a relay and power feed so you can't just use the factory wires.
Interestingly, the Nautilus Compact is listed as having a lower "absorbed current", whatever that means, of 9A at 24V versus the Nautilus' 18A at 24V, yet puts out 139 dB versus the Nautilus' 115 dB.

(The stock horn is on a 10A fuse.)

The products spec sheet sez "Absorbed current (at 24V)". It also lists the horns' "Nominal current" as "12 o [sic] 24 Volts".

I got the motorcycle version, because I may use it on my motorcycle.

Of course, I do use the factory wires. They turn the (supplied) relay on and off. Easy. I'll do a video on the install.

Yeah that is the other way of doing it. I did't feel like being on my back to do it, but in the end either method works just fine.

I suggest using recycled parts. Horns can be found in salvage yards for a few dollars and some effort. Find the model you like and unbolt them. Most salvage yards also sell batteries, use them to test the horns before you buy. Mercedes Benz have nice ones and they have the frequency stamped on them.
