Air Horn Car Install and Relay Wiring Instructions

Today we're installing some cheap airhorns from eBay/Auto parts store. Hope this helps you with your install.

[@FurryWrecker911]

I absolutely appreciate that you sampled the audio 10 seconds in. Really helps us decide if this is the tone we want before proceeding through the install.

[@StrangeGarage]

You gotta show people what they're in for, otherwise people aren't gonna stick around.

​@StrangeGarage iv ordered a twin horn, is there a way to make them louder if it's not loud enough in the location I put it? Wanna try to hide it incase i get pulled over but still want them to be loud

[@IanYGath]

Funnily enough I just bought one of the kits (with the relay) and now here you are showing me how to install it. Strange world indeed. 🙂👍🏻👍🏻

[@datoyguy1]

Same here dude😁👍🏼

[@JJ-se5cn]

Thanks for the great video explaining the relay wiring. Simplified and easy to understand.

[@papasDzz]

Dude gotta THANK YOU finally someone explained something that we all can understand,the way ya explain install was like hanging with yr buddy doing it n can understand not like those many veage or to high tech ya can't understand so thank you I learned more in yr short video then watch twenty of the other bogus ones 5star!!!!

[@marianner.1340]

Nice video. Clear concise and to the point with everything I needed to know about installing this device in my Honda CRX. Thanks.

[@chaplainlee]

You have the best and most clear explanation of all the videos I could find. AWESOME job. Blessings to you all.

[@StrangeGarage]

Thanks man, I'm glad I was able to help!

[@frankvalenzuela5420]

I hooked it up to my existing horn all I had to do was change the 10 amp fuse to a 20 amp & it's been working fine

[@alchance662]

This is MY goal. So the OEM wiring handles the OEM Horns PLUS the Air Horn? What is the amperage draw on your Air Horn so that I can make sure not to exceed that?

[@gpslightlock1422]

I've been hit a couple times from someone backing into me while I was laying on the factory horn. I just want a louder horn. Thanks for the nice video.

[@coreysanders7821]

Simple snd straight to the point. Just how i like my videos. 👍

[@andrescaban6743]

Great video man! All the other videos I watched did not help. This one was very clear and easy. Thanks dude

[@szeglowskip2]

Man I'm so glad I found your video I've been trying to find out how to wire this damn thing for like 3 days

[@StrangeGarage]

Great, glad I could help!

[@craftsmanconnection]

I normally work on residential wiring, and also a former army mechanic, but I have never really gotten into relays and what’s the point of a relay? So for the real question, the relay has 4 connections: #87 on relay to compressor, #85 on relay to push button horn switch to ground., #30 vehicle fused circuit, #86 on relay to is to the “live positive “ point of original horn. I have a 2021 F-350 with upfitter switches in the cab, and I was planning on switching those on for a quick second to operate the air horn, but now after looking at wiring diagram....I’m not sure I get all of it. With the wire from #87 on the relay to the positive on the compressor is a no brainer. I think #30 goes to a permanent source of power, but I was planning on using my upfitter switch that is fused. Do I need to just run power straight from the battery to #30 with a fuse? What does the “live positive point of the original horn have to do with my new horn, if my positive power is coming from my upfitter switches? I have the 2 horns and the compressor mounted, with the positive and negative wires connected and run into the engine compartment by the upfitter fuse box.

[@Cronicbubble]

Great video....been never used a relay before and I've been scratching my head all day.

Wicked vid! Very clearly explained. Thanks

[@djlancematthew]

Very happy I stumbled across this video! I saw the plastic horns that you had and I’m glad I got to hear them. I don’t like the sound of them. I’m going to have to look for something else!

[@kevingrabkowski5505]

Great video and sound quality 👍

[@pos6666666]

Excellent video. I'm glad you mentioned to not using the existing wiring for your horn. I was just thinking that it probably wouldn't be enough power. And need to use that relay.

[@StrangeGarage]

It MIGHT work, but there is a reason those kits come with relays. Thanks for watching and commenting!

[@TATEXPRESSINC]

Shoutout from TAT Express out of Hutchins, TX

[@13Danb13]

Thanks so much for the basics. I just installed the same horn from Harbor Freight in a 1995 Mazda Miata. My wife didn't feel safe with the little squeak horn that is in the car because trucks simply don't see her. Installation was a challenge in relation to location. I ended up taking the hood latch assembly off so I could install it in front of the radiator. Worked out great and they will definitely hear her coming!

[@nicksgarage8295]

How loud is it. Thinking about installing it on my bicycle. Is it close to a train horn???

[@reycorral1097]

That's a good video very clear thank you.

[@1620GarageAndFarm]

Once again, MY MAN ... I was just looking at these on amazon for my UTV ... Halloween is coming up, and my kids and I will be taking the UTV... And it will be HORN READY ... And recording GoPro footage :)

[@markkimball1569]

Lol I always took it for granted having a fire truck horn. Now I’m retired I need my fix !! Lol. Yea part of the job is fun ! But it’s work ! 👨🏻‍🚒👍

[@StrangeGarage]

I really like those horns. I kinda got it by accident: wandering around a junkyard when I was in highschool. Dude sold it to me for $40. 17 years later I still love it!

[@psp372m33]

Perfect video lol. Exactly what I was looking for 😂

[@StrangeGarage]

Glad I could help 👍

[@peteracke2209]

Simple and logical..good video..thanks

[@joeygauna9940]

Great video not super long but very detailed. My only question is how do you know what’s positive and what’s negative for your relay unless energizing the coil doesn’t matter which way you out it

[@johnchristopheragnick8304]

Excellent video.

[@tadtravis]

nice video bro! I have BOTH of the horns and I'm trying to connect them BOTH together for a 3 note blast!!!!!!!!!!!!

You can buy the wire harness off of amazon for pretty cheap

[@ScorpioYardWorks]

Great video! Thanks for the explanation. Wondering if you have any leads to where I can get a fire truck horn like the one on your truck. Sounds nice!

[@kevinmurphy9982]

This is by far the most simplified video I've seen. My questions are, what gauge wire do I use and what should I ask for in terms of the relay? Thanks

[@StrangeGarage]

Thanks man, as long as it helps then im happy. 12-14 should be fine. Relay should be 12v 30 amp, normally open.

[@allenmckinney9533]

I got that 1st horn and before I put it on my truck I rigged it up to a board and brought it into work used it to scare a guy I worked with. I loved having it on my little s10 when people looked around for the big truck that honked at them.

[@oconner78]

I installed one on a 1978 GMC and one on a 1966 Rambler American and just hooked it up in place of the original horn without a relay and never blew a fuse. Also recently hooked one up on a 1992 chevy Silverado and never blew a fuse but it wasn't as loud as it should be

[@AntonioClaudioMichael]

Are these style systems with the small included compressor are they constant duty compressors or are they short burst compressors?

If your horn runs on a relay already, you're fine

[@joshuawheeler4404]

I have seen my friend add this same one to his existing horns and didnt blow any fuses with all 3 wired up

[@3nglehart]

do you have the link of the single horn? love the sound of it

[@careymitchell4731]

I installed one of the red ones years ago. It sounded like a wheezing mule. Took about 1 second for the compressor to develop sufficient pressure to honk, so it sounded ridiculous. Removed it the next day.

[@Comopr02]

So I plan on wiring up a switch that allows me to use my factory horn or my train horn, but what I was hoping you could answer for me is...How do you know if the factory horn is Negatively triggered or Positively triggered? Is there a way to test cause that makes a different when wiring up the Relays I have to connect. Thanks.

[@mitch5077]

Thanks for explaining the relay

[@Moksoory1]

If you lay on the horn for a long time is the air horn still loud or does it die off when the horn is pressed for to long. I intend to install one and need a loud horn for a long duration of time ~1min

[@barrywetzeljr8050]

What was the name of the horn you installed on the Nissan?? I like the sound and would like to order one myself

[@quickieswithscottechristie]

Is there a way that I could just wire it to a battery and use at home because I don't have a car but I need it at my house so I can set it off at certain times of the day... I appreciate your help

What kind of fire truck horn you have on your f150? And how much? I need it in my life.

[@dcrican762]

Absolutely love your informative video. I want to do exactly that. But keep my factory horn connected, with a dedicated separate button for the train horn. How do I do that?

[@StrangeGarage]

Just gotta run a hot wire from the battery into the cab, attach it to a button somewhere in the cab, then run another one from the button back to your relay, and Bob's your uncle. Make sure that wire is fused too.

[@dcrican762]

@@StrangeGarage the wire from the button Back to what # Relay? Which train horn is the loudest you recommend under $100. Thanks

[@victorsvidss]

Great video!! Some advice if you make something like this again is to use mabye slightly better camera angles when showing the wiring. Otherwise great explanation 👌👌

[@StrangeGarage]

I'll admit that I focused more on how the system works than how I personally installed mine. This is just because every car is different, but all criticism is good as long as it leads to improvement. Thank you!

@@StrangeGarage I actually used some tips from your video to install a truck horn in my old car! 👍

[@Emsdowns04]

This cleared up a lot of confusion I had. My only main question is, when you unplugged your regular horn terminal, did you just did stick the wire into it or was there a male/female adapter to connect to it?

[@StrangeGarage]

If memory serves me, the factory clip was a female spade so I crimpped a male spade to the end of my control wire and shoved it in. Easy money bro!

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?

[@guillermonieri4203]

[@user-nx1yy8me6d]

If I hook up the power for the relay to a fuse that is only on she the ignition is on would this separate the horn, like when I lock my vehicle get the regular horn and she I'm driving and press the horn get the loud horn?

Thanks appreciate all the info take care

[@enriquelopez9609]

Good video, you explain it very good. One question how to connect the wire that will blow the horn from the steering wheel

[@StrangeGarage]

Get a wire terminal kit with crimpers. It will have the correct male spade terminal and you use the strippers/crimpers to install it.

[@enriquelopez9609]

Ok, thank you

[@leodiaz1784]

I just bought the single horn and am going to install it but I'm wondering, could you still keep the stock horn wired up and just splice in the relay to activate the larger horn at the same time, of course while powering it directly to the battery? That way, you would have two tones (the stock horn and single trumpet horn) or would it be best to just simply disconnect the stock horn and run the single trumpet horn?

[@StrangeGarage]

Yep, totally can. You can run both horns in that configuration as long as you use a relay.

[@leodiaz1784]

[@sammiebg9037]

So I'm a bit late to this, but mine sounds like a clown car. Which is absolutely hilarious and does catch the attention of cars around me, but not what I was going for at all. The compressor "spits" out air in short bursts instead of a prolonged burst. What did we do wrong?
