Horn Question / Replaced ‘Clown Car’ Horn

[Teleguy11]

Lots of complaints have been said about the terrible horn in the MkV.
Has anyone done a horn swap they can recommend?

I keep sonic milkshakes on hand to toss at cars.
Will never be caught pushing the horn again.

I wanted to blow the horn at this a-hole but remembered how wimpy my Supra sounded so I blew my Hella's in my STI when I got home... scared the crap out of me.

I see people still aren't using the search feature.

I know there has been talk of … but has anyone actually added the secondary BMW Z4 low pitch horn to their Supra?

My BMW tech has ordered one for me and plans to install.

Just checking with others…

it sounds the same as my i3?

Dual horns would make it sound like a big old cadillac lol. Super rude beeps.

There was one member based in the Middle East, he has done this mod.

would be great to see some pics of your installation by the BMW tech !

Is it a plug and play thing replacing the stock horn, or are you adding a 2nd low pitch horn? If you're adding a 2nd horn, please show pics of how it will be wired.
I understand from previous posts that the front bumper cover must be removed to access the horn.

~ I will be adding the 2nd bmw horn (low pitch)… the bmw horn harness / connectors are being purchased as well. This way the existing horn wiring can be spliced and they can work in unison.

Pics to follow once installed.

I'm taking my GR to have the front bumper cover painted to repair rock chips this Monday. They are going to remove the front bumper cover which should provide access to the horn.
The paint shop is ok with me working on it while the horn is accessible.
Pics of reliable wiring to add an additional horn would be very helpful.... thanks all...

This video shows you how to wire it. Just power and ground.

I just completed the horn upgrade using the write up in this thread: https://www.supramkv.com/threads/replacing-horn-with-piaa-sports-horn.10997/post-202047

Also sharing some wiring diagrams from PIAA if it helps.

I haven't had the chance but anyone check what horn is in there supra physically. And what is listed in the parts catalogue/parts ordering from the dealer (thats what should be in the car). Maybe they missed something while assembling it.

On ALL of them?? That's kind of like the guy who committed suicide and was found shot in the back four times - a little hard to believe. I think the Germans/Austrians decided that, if the engine and transmission were both going to be better in the Toyota car, something had to be better in the BMW iteration. Here! Here is your F'ing horn Toyota!
