FARBIN Horns Auto Horn 12V Car Horn Loud Dual-Tone Waterproof Electric Snail Horn Kit Universal for Any 12V Vehicles Black (Black horn, 12v)

These were pretty difficult to get to fit in place of the stock horn, but once I was done I was very pleased with the sound. The kit comes with a low tone and high tone horn that are a minor third apart just like most factory horns of this style are. So, these are two-tone unlike your standard little "beeper" that many of you are probably here to replace.Definitely get it with the harness. I'm not sure I would trust the stock horn wiring to handle these two horns at once without blowing a fuse, and it additionally made the installation process a little easier for connecting the two horns.Before you go to install these, you will need:- to know how to crimp wires, and have a wire crimper/stripper(you probably already own some. they're like $5 if you don't)- butt connectors (yes, they're called that at the hardware store)- ring/fork terminals(for cars with only one horn wire). Connect the white wire on the harness to a grounding point with one of these terminals if your car only comes with one wire.- a set of sockets and screwdrivers. for most cars you'll only need a 10mm socket but might need a few different ones to get access to the horn.Whole process took me about 45 minutes including trial and error. Check all grounding points before you try the horn and make sure that the hood closes, too. Will update this review should I have any issues down the line.

Very loud, good diagrams included for wiring

Simple to install, complete kit, decent quality, but the loudness isn’t much (I’d at all) different than any standard car horns. They are functional and I hope they last.

Easy to install and sound quality of horn is great!

You have to remove the plastic grill. On the Sienna the "hot" or positive wire (green and white wire) for the horns attaches by a plug to the horn, and the ground is made through the metal bracket that bolts the horns to the chassis. so there is only one actual wire going to the original horns. On mine, it turn out that the ground was no longer working due to bad connection from rust, corrosion. It's helpful to use a test light before jumping into this to make sure that power is getting to the horn, and that there is not a problem somewhere else (These other problems could be the fuse, the relay or the switch in the steering wheel). The test lights are cheap to buy and very useful. Assuming power is getting to the horn: Installing these aftermarket horns is initially confusing because each new horn (high sound/low sound) has two spade tab connections while the original horns have only one. If your green/white hot wires are in good condition, you can just use a standard male spade connector crimped onto the end of one connector wire to go into the plug; you don't need a special Toyota connector or adapter. Or, you can do as I did and just cut off the plugs and crimp a new connector on. I also ran a new ground wire from the grounding screw in the sidewall, near the windshield wiper fluid fill and radiator fill, to both horns. The hot (green white) wire goes to one tab on the horn, and the ground wire goes on the other tab. That's it. The horns are plenty loud, probably louder than original. These snail horns are bigger than the original horns, but they fit behind the grill if you configure them properly. On mine, I installed the horn on the driver's side with the tabs facing backward, and the one on the passenger side with the tabs facing forward. Make sure the opening to the horns is facing down so that water cannot accumulate inside the horns.

The horn broke down it work fine as was loud,but I wanted a train horn sound or ships horn??? Cold weather is rough on little 4 cylinder cars like Hyundai!!!

purchase with wiring kit - fairly easy - mount positive side of harness to + side of battery terminal, plug in the two wires to the factory horn wire, then wire up the horns to the harness plug. The harness is short and may need to cut and extend one set of the wire.

Sounds like a Honda Accord, survived a flood.
