My car only came with one horn, is it okay to wire both of these horns into the original circuit? Will they both receive 12 volts?

Yes, this is what I did with my 2017 Nissan LEAF. The horns have a + & - Terminal (does not matter what connector pin you use for +) If your car only has one lead to the horn, put that to one to one connector, and make a short pigtail that you connect to your car's chassis or ground. That is it. Each horn is mechanically tuned to different notes, and together they will get everyone's attention when sounded.

I am not sure if it will work for all vehicles, but I parallel wired both horns into one circuit on my 2007 Miata, and it worked without issue. I did not need to use the relay either.

Yes you can either cut into the wire as suggested by someone else or cut the wire going to the horn put a female connector on the one end. Then take the remaining wire from the horn and the new horn wire and splice the two wires together into a male connector and join the two together. I always electrical tape the connectors after connecting.

do NOT wire direct from the alarm - run the horn wires from the alarm to a relay and then run power from a permanently powered 12v circuit on the car9like the one that is powering the alarm, through a 10a fuse to the relay main input and then out to the horn +, and then run a wire from the horn - to the screw where you mount the horn to the vehicle (assuming it is negative ground like virtually all post 1950 cars)

Yes. However I strongly suggest installing a 3 position switch that allows you use both your oem horn and the train horn. I also have another switch that activates and deactivates my air compressor. It can be easily done by any car audio shop.

Barb, you might need more wire, depending on where the horn is located. I had my original horn replaced (because now most car horns are weak) so additional wire was not needed.You will really like this horn.

I installed these horns (2), on my 2013 Genesis Coupe to replace the stock horn, no electrical problems and the horns sound great. Loud, attention getting.

If you're replacing existing horns, you won't need to change anything as the OEM horns will already have a suitable fuse & relay. If you are adding these in addition to your existing horns, you will need to add a suitable relay. I replaced my OEM Toyota horns and these sound great just make sure you use the Hi & Lo note together. I was very happy with them.

I would get more wire (they don't supply enough) also different connectors. . (Butt, male and female connectors. .heat shrink style if possible) ...I didn't connect to my truck horn, I installed a separate switch..It's not too difficult. .Takes some time but is fairly simple. .The difficulty is mainly based on how you want your setup to be.

Yes you can hook it up to your existing horn.. instructions are simple to follow

David, It will not work connecting it to the existing horn circuit alone. Here is a site that has very good installation instructions: http://www.valkmotive.com/installation-nautilus-419-519-619-vm2-nm2-gp-418-404-415. I hope that helps! JD

Steve, I installed the Fiamm 72112 Freeway Blaster and the Fiamm 72102 12 V High Note horns (I really think that you need both) on my 1966 MGB that has a 20 Amp Fuse and a stated max Amp draw of 3 1/2 amps. I had planned on installing a relay, but horns worked so well that I never installed it. I would simply install one or both of these horns and if they blow a fuse, then install your relay. I hardly ever use my horn, but when I do they do get Semi drivers attention. Best $30+ dollars I ever spent. I hope this helps.

Most alram systems have a 12volt DC output for the siren or in your case the horns. Send that postive voltage wire to the plus terminal and the negative terminal gets connected to ground.ED

You don't need the solenoid. The horn has it's own solenoid. I made the mistake of buying the compressor together with a solenoid only to confirm with Wolo that the horns already come with a solenoid.

unfortunately no. you will probably have to fabricate the wiring harness. it just depends on where you locate the horns.

Yes, if you use two horns you will need a relay. If you use one horn a relay is not necessary. It's a good idea to use an in line fuse if the circuit doesn't already have one.

The horn says 30 amp fuse, but your horn button circuit to the horn relay is much smaller. I have mine connected to stock horn wore with no problem.

I Cant see any reason that would not work, just use the 12 volts to operate the solenoid when you want to blow the horn. I have had this horn and on my ford F250 for 3 years now with zero problems.
