DIY: Install a Train Horn for Cars & How to wire a relay

Today, I'm going to show you how I install a train (air) horn for my car. I also show you how to wire a relay to the system. Will also have a diagram for you at the end of the video.

Dude! I've tried so many different videos on this and i just so happened to search for "How to wire a relay for a Train horn and your video came up.Thank you so damn much for finally explaining this in an understandable and easy way.You helped Significantly.

[@martindelgado1484]

Your awesome👍🏼 I watched tons of videos & still unsure of how to install an air horn. Then you came to the rescue....there’s nothing negative to say about your video. I got past your accent within the first minute of the video. I love the way you did a wiring layout to explain the connection & direction of wires. Videos with American accent were still very unclear to understand the instructions. FYI something I’m sure you already know....I would put an in line fuse from battery to pin 30. WOW, I didn’t know you have so many videos!! You saved me so many headaches hahaha🤪

[@melvis2017]

It's so great I finally found your channel.you are a great teacher appreciate the way you explain things thanks once again for the efforts and for sharing this with us appreciation .u make saving time🇩🇰🤣👍🙏

[@How-dc8rx]

I used to have a corolla, the horn is very ... weak. I have a minvan now. Much better, but still nothing like an air horn. I wish I had kept the air horns I had in the corolla. I'm going to put some in.

[@omw9965]

Explained everything very good, details are good for most but some know it alls can just fast forward or dont watch at all if youre a genius, but as for me I say it was a great video

[@garfieldnelson4724]

Hey Bro, you are a very excellent teacher. Good job.

[@lomgshorts3]

I would use an empty freon tank as an accumulator for the pump for instant sound. There is a half second wait for the horns to start, and the accumulator would eliminate that wait time.

[@colinallenby6700]

Show your video would like that it would be instent

[@judgejury3230]

Great job!

[@gerrybmalkin]

thanks I needed the electrical schmetatic

[@eurgio7474]

did the horn need a minimum amperes ?? (Ah) or just 12v is enought ? I have a homemade battery from 12v and 6.8ah is it enought ?

[@gns-gu8xh]

Great video I do have a question, I have this same air horns and I would like to replace the existing horns under the hood that have 2 wires each, with the air horns and using the steering horn button, their is a 15 amp fuse in the fuse box, can this be done and how. Thanks

[@FatBoys69187]

Nope

[@Fkidd702]

Great video man! I just bought a cheap one at harbor freight and no instructions

[@92aussiedude]

Super helpful, thank you

[@j.stormtracker4407]

Good video.....your video helped me install my air horn on my car. The only thing different I used was an actual older horn button I got locally....otherwise, your video helped. Not sure if my Honda is "horny" now LOL

[@stewartmackenzie7304]

Very good mate

[@thatradkid]

I'm just waiting to hear this Corolla on the 280 lmao. Nice video man!

[@vuaeco]

It has been there! :D

[@HillbillyRednecking]

The one thing I remember with these horns, it's a higher pitch horn sound, normal sounding if you're from Europe but it doesn't make a deep manly US semi truck tone

[@themipapadakis2449]

Great video,explained really well

[@hugoescobar6401]

Gracias loco me sirvió mucho tu explicación

[@truenorthmuskoka9077]

Great video. By far the easiest video I found to understand how to wire. Do you need a fuse in there somewhere.

Thanks a lot

[@M5guitar1]

Awesome thanks

[@sirmeliodas608]

ping tirty haha lol your amazing

[@drones4964]

Is there a way to set this horn up to run from a power supply that connects to mains power? So that I can avoid the need for a battery pack? And have it constantly powered?

[@Grandpasaab]

How many Amp fuse do you suggest to put inbetween the + and number 30?

[@rohanndutoit4544]

Did you figure this out yet? Looking for a fuse myself.

[@Grandpasaab]

@@rohanndutoit4544 don't remember think I went fuseless

Hey mate what wires are the best for this

[@simoncox7805]

If you want to know how to do it watch this vid. Does what it says on the tin. Thanks mate.😀

[@SorinR]

hello to were i have to connect the new switch/button that came with the kit i have an old switch/button that i wont use it .can u show me or explain to were it will be attached the + and the- of this new switch/button

[@Shane23Armada]

Did you use a separate switch ?? I have one of those but brigestone. I didn’t use separate switch

[@vuaeco]

Yes, I used a separate switch. I tried to use the same switch on the steering wheel but it burned out my fuse.

[@mramnauth0]

@@vuaeco please help me to install a separate switch, I tried and the horn won't stop blaring. Switch not controlling it

[@mramnauth0]

Help please!!😢 I was just trying to install a GAMPRO 12V 150db Air Horn, 18 In, and it's not shutting off. I bought a separate switch that have a black and red wire, how do I connect the switch?

[@Andropolies]

First one i understood not great but enough THANKYOU

[@tonyworthington5820]

Excellent thank you very much for this video,very well explained,best one on KZbin

[@mrnajee1]

i notice that you did not use a fuse with your connection, what is your reason?

[@stevelerch27]

I'm guessing the "Switch" is your old horn wire? The positive one that usually attaches to the old wimpy horn?

[@vuaeco]

No, I used a completely new circuit. I did try to use my old horn switch which is on the steering wheel but it burns the fuse immediately because the amp draw is too much. So I have to make a new circuit and install a higher amp fuse (20A) in it.

[@nicholascroft520]

Stephen Lerch yes exactly. It only takes 200mA to throw a relay. If he's burning out fuses, he has it wired wrong. You would essentially unplug your old horn and plug it into 85 & 86. With FUSED power to pin 30. Any other questions mate, just ask.

[@rohanndutoit4544]

As Nicholas stated it is quite simple. I literally unplugged my old horn and threw the live on 86 and the ground on 85. Not too sure why it would be a problem. I must add from 30 to the battery I put a 20amp (no idea if sufficient) fuse in and it works like a charm. Was quite nice not to have to wire new ends etc. Hope that helps.

[@aldrin31able]

How much current drawn for a compressor?

[@PlanesofExistenceUK]

Does it still need to be fused?

[@randommisshaps7]

Snowy J. Moore yes

[@FatBoys69187]

Always use a fuse. Common sense

[@martinhristov000]

What is the diameter of the tubing, i have not received the horn yet, but i bet i'm going to need some more tubing ?

[@erikandvivianrossizalkus9329]

Martin Hristov about as thick as a cigarette

[@jerrysanders359]

what do you hook the relay to

[@dallaspilotcar9293]

my horns that look just like this the diagram says that 30 is supposed to have a 30 amp fuse in line. Why do you have 2 wires going to 1 pin on 87 ??

[@user-sj1tt3ie3z]

Hope the video was good. If I buy one of these horns, I'll figure out the wiring myself. Times have changed, & setting through youtube commercials would be lame.

[@asitsamal8031]

How to buy this horn

[@jorgemorales1141]

do you NEED the relay? im trying to put oneof these on my scooter. i know how i have to wire it up just if i dont have to thatd be great.

[@vuaeco]

That depends on how many amps your horn needs. But in general, if you have a high amp push power button (20A or more), you won't need a relay.

[@jorgemorales1141]

im not sure honestly im putting it on a scooter. i wired it up to the horn and it goes fine but ive done a lot of other electrical junk so im popping fuses TnT so i gotta upgrade my rectifier or something idk but i think i got it wired up fine idk TnT lol

thanks for the info :J

[@laurentcalkoen9203]

Hi, I installed this on my car but the volume of the horn really really soft.. What could be the issue?

[@vuaeco]

Could be the pump. The pump has to pump fast enough air through the horns. If you don't have good flow of air through the horns, it will sound weak. There are a few reasons why this happens. Your pump might be defective, or your battery is too weak, or there's an air leak in the tubes.

[@laurentcalkoen9203]

It sound is always consistently low volume.. Battery is standard 12V from a VW Tiguan 2018 model - is that okay? Don't they all work with 12V car batteries?? I Checked the pipes and they are okay.. Do you think the compressor pump is just a crappy weak one then? Get a new pump and try?

[@vuaeco]

I'd try a new pump and see if that's better. If you have a regular compressor (for pumping air into tires), you can try that.

[@gabrielpichardo1492]

You are probably not using the relay correctly. When this happens it's because the pump needs power directly from the battery

[@MrAllancord]

what would happen if i didnt use the relay? I will just use a push button switch.

[@MrAllancord]

btw im using a lithium polymer 4s battery with a 70c rating. Im just using this for new year as a portable air trumpet.
