How to you hook this up to a switch in your car?

[@Lesscoelectronics]

+Harrison G connect the car's horn wire under the steering column to the coil on the relay you wired the air horns up to. (pin 85 or 86) depending on how you wire relays...

[@Lesscoelectronics]

see my latest video here, its shows exactly how to: kzbin.info/www/bejne/hKm6knmPhK1rgqc

[@camwalt.4197]

Almost everything that any person would need from a video about hooking up air horns is done right out the side of the screen. Good job bud You really helped

[@panasonicht75]

It would be most helpful if what you were doing was captured on screen.

[@hottlimited]

Panasonic Ht75 hell yea !

[@spacemanspiff2146]

Yeah I can’t tell what this guys doing. Put this been on that pin for this wire here but really all you see in a horn

[@samuel649]

For real like I’m confuse I’m only looking at the horns n the compressor

[@karams49]

can you remake this video ??

[@eduardorangel8821]

Can't see anything

[@adamlee7299]

Hello im trying to hook up my air horns, the wires comming from the stck horn has two wire, white and black do i just use the black only

[@steightofthehart7899]

as the clock is counting down . . do i cut the red wire or the blue one ?

[@thomaslockley945]

so the red wire is ,"protecting the circuits" an is also hooked to the main hot wire?

[@LUISGOMEZ-pr5xg]

wau the cornets I love them thanks for your videos

[@HewAndAwe]

BigDave may of been trying to ask the same question (bad English) and I've got to ask - years ago I fitted a set of theses to a car and just used the wires + & - from the old horn and seemed to work just fine. I'm about to fit a set to my MX 5, the new horns didn't come with a 'relay' nor have I got a clue what a relay is - do I really need to bother fitting it the way you have? The horn I have bought says its 12 volts...

[@TheiaSilvermoon]

i want to install a train horn in my 2008 honda civic coupe but... idk how to go about it. rn i have a squeaky sounding horn that doesnt fair well when i need it vs a-holes on the highway or something...

[@braveheart6850]

I have a 2013 Sonata Limited and I replaced the horn with a small compressor horn from Marco Automotive called Tornado. Purchased on amazon. It came with a 4 point relay. Following is the hookup for the relay and horn. I had to take a picture of the relay and then zoom the pic to see the numbers on the terminals. 87-Is fed from the positive 12 volts on the battery terminal. Install an inline fuse. 30- Goes to the positive terminal on the horn 86- Goes to chassis ground 85- Is fed from existing wire that comes from the steering wheel. This is one of two wires that are part of the harness of the original horn. The black wire has a constant 12 volts on it. The green has 12 volts applied when the steering wheel button is pressed. When 85 is energized from the green wire from original horn, it energizes the coil which lets 12 volts flow from 87 (12 Volts from battery) to 30 the positive on horn.

[@robrodriguez4866]

ted mcelhone you sir are the man

[@drewscalice6602]

Can I get a Bluetooth relay so I can control it without wiring to cabin?

[@FreeAgent01]

@ 8:00 I'm lost from then on u wired the fuse n never used it

[@mitchodds]

Is the horn button not 12v? I've never installed one of these but I've always wondered why you need a relay. Why can't you just take the wires off of the existing horn and put them on the +/- of the compressor? Thx!

[@kavinsp]

Mitch Evens the voltage is 12 volt but the ampere is too high for the stock wires to handle

[@iamasmurf1122]

Kavin Jebastin bullshit !!

[@iamasmurf1122]

You can in cars the relays are exactly the same all I did was just that , took out old horn hooked up the wires that already exist , all these things with saying wire up relays new wires etc is all bullshit

[@nudgek]

I'm guessing the horns can only be as loud as the compressor is that right so what compressor would you recommend for very loud horns?

[@comanderjuul]

A very big compressor... from what I've read, a 3L (~1 gallon) tank and a 20cm tall/long compressor should be good for a nice truck sound.

[@bananasslamim3005]

IL love igniting helicopterers had boat horns lol

[@Kitana68]

More visible time on the relay less on the compressor will help.

[@matheuirias7683]

sir excuse me ...I live in Austin Texas where i can get that ....wish store ...

[@janetoss]

keep up the good work. very helpful.

[@bigman7293]

What if the relay and wires are set up opposite you said it should be in your car? The one I bought has the 12v positive supply to 30, ground to 98, positive power to motor from 87, and blue wire to switch between that and positive supply to 85. It's not working at all. Do you know what's wrong?

[@soundnicetome]

This tutorial would have been so much better...if you could have taken a little more time and let us be able to view the relay and its connections..most was not in view while you explaining things,especially when it comes to hooking up the relay etc?

[@iamasmurf1122]

soundnicetome if you are installing these in a car or whatever that already has just a factory horn , I don’t even know why you people go on about it , the factory relays in cars are exactly the same , all you have to do is hook up the wires from the original horn , I mean are you that stupid you can not work that out ?

[@subaru4wd1]

Just installed exactly as show. But with an after market push switch. Having and issue of the relay sticking on randomly

[@ashleyschooneman2998]

So the red plastic ones are better ?

[@jackal58590]

roger s did you get an answer?i also want to wire up a second circuit air horns,keeping the car horn.i want to wire a separate circuit with its own switch preferably off the battery.without touching the car wireing.did you get any answers.thanks.

[@YamahaRider-mm8bh]

I would just put them under the hood right next to the air box, perfect spot for keeping them out of the weather.

[@WhatTheHeckTV]

thanks it worked great for me, the horn to car horn threw me off on the directions

[@MrStrengthz]

I've bought a set of horns but my car only has a positive wire and no negative how do I come about that? Or just ground the earth to chassis??

[@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

[@justinhmarley]

Can you write out wire hookup in description? Still cant get mine working.

[@ThatDudeHandy]

i need help on mines before i do it. My question is can you connect more than one 12v air pump to single 30 amp relay? i used a 30 amp wire for led bar light wires. its ready to go with the 30amp relay and fuse.

[@markpayne3529]

hi I have a mission on my hands, im putting the last three remaing horns from my Dixie horns onto a alloy bracket and mounting them somewhere on my 2004 Toyota estima. im looking at a 5 gallon suspension tank mounted next to the space saver under the car with a 200 psi compressor next to that,, at this point im hoping that we have some serious noise. just not to sure how to plumb it all up and wire it.

[@jaxoncostello7766]

Yeah I would have to completely agree with the comment it'll be nice for us to see what you're doing. It would be helpful to see what each wire is connected to. Without reference to a wire's connection the info is kind of irrelevant.

[@steveyamaha9073]

question i had ordered a train horn from facebook.i did not get a compressor and the horn has a soliniod on it with 2 wires ans an air inlet.how do i wire a diode for it

[@elmerjfapp5730]

"ching chang metal" proudly presented by amazon

[@AntonioGarcia-kg9xo]

i bought one of these but it dirrent had cables ... wat cables do i need ?

[@braveheart6850]

Does the output from the relay to the horn go on the positive or negative terminal of the horn? Then the other terminal from the horn would go directly to the chassis ground?

[@armankholesi7174]

hello, how can i keep my OEM horn and use this a secondary horn? i guess i will need an extra switch which will be inside the car but where should i get the power from to the switch then to the relay?

[@Lesscoelectronics]

+Arman Shokouhi Rad Sure, you can do it either way, that's the beauty of doing a custom install!

[@armankholesi7174]

+Lessco Electronics so the switch that will be in my car will get power from battery and go to relay, correct?

[@Rjelectricfingers]

Q? If i get a more psi electric compressor in range of 21psi vs 18 stock ! Will it make the trumpets sound louder ? I think it would ? Wha u think? Thnx

[@instagramgilleyswag3.757]

It would help if we could see what you were doing

[@MrFreddyelgato]

Hi there how are you my question to you is in order to install an air horn do we have to disable the factory horn on the car or both horns will be honking at the same time????

[@RABERTRON]

I want to get your Wiring Sheet. How do you Wire it to a REMOTE Botten???

[@mdff3]

Looking for that PDF you were talking about?

[@key2pwr]

How do you install 12 Volt 12V Dual Air Horn Kit as a second horn with its own button?

[@Lesscoelectronics]

Tell me the details on exactly what you have now and I'll explain it all to you.

[@adamoneale4396]

SunrisePonyFarm red to battery and horn, black to vehicle chassis. I ran my black and red wire through the fire wall, into a dash switch and grounded to my seat. Dont bother with relay its only to protect car electrics and you are just adding a corcuit

[@qstix9733]

is it, the more horns the better / louder?

[@1000tCSX]

This video was very helpful! Thanks

[@ashleyloera1782]

i don't understand the fuse part can someone explain.

[@kentcan]

How do I know whether or not I need to use the included relay? I bought this dual air horn system and installed it on my 2004 F-150 without the relay (the instructions seemed to indicate it was optional). It worked several months just fine. Then in started blowing fuses every time I'd push the horn. I took it all apart, cleaned the compressor and connections, and reinstalled. It worked again for a couple months, and now it's shorting out again. Would I be better off using the relay, or would it be redundant with the vehicle's electric system?

[@matarazzo209]

Increase the fuse if it's a 5 use a 15

[@matthiastice8322]

Do you need the relay. I put in this exact system and left it out. Is in nessary for any reason?

[@ryancarnahan3257]

No, I hooked up two horns to the same system my factory horns were wired to and it works fine. No need for relays or 90% of what this guy is doing.

[@jimstephon3425]

Nice Tutorial !!

[@jimstephon3425]

It is imperative that you use colossal quality automobile horn system inside your automobile which can alert the actual pedestrians and other cars on the road with time. Use of train horns for car is an ideal option which can organized you free from all of your high quality horn plan requirement. This is a few things I have learned from your video and from the website pbmissions.com too. Thanks for delivering information on Truck Air Horn. Thanks!!

[@NeilKudro]

Cant you just cut the wires of the old factory horn and directly connect the new air horn to the old factory wires?

[@joshwilson2512]

no you need the 12v 30a relay or the compressor will not get enough power to run it

[@allangray4744]

good video you explained it pretty well

[@Grandpasaab]

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

[@Evrenthewrencher]

Awsone video thanks

[@gns-gu8xh]

Can you connect this horns to your steering horn button?

[@garysandford366]

Hi I’ve just got twin air horns and I’ve seen a diagram but I’ve got a cylinder with two black wires on it but we’re do the wires go and I’ve got a five peace connector block anyone please

[@TheGoodbabies]

One video I watched said I need to put a diode between pin 85 and 86 your thoughts please, thanks John it's for my motorcycle .

[@Lesscoelectronics]

kzbin.info/www/bejne/hKm6knmPhK1rgqc

[@tfgdj94694]

sorry to say but you got it slightly wrong pin 30 is always connected to constant 12 volt and pin 87 is connected to your device (horns lights etc) not the other way round of course it doesn't really matter that's usually how most diagrams have it

[@Lesscoelectronics]

16 gauge... Even 18 gauge will suffice on a kit like this here. you only have to worry about wire gauges on the kits with the big compressors.

[@gns-gu8xh]

I have my steering horn button with two regular horns with a positive and negative wire on them and a 15 amp fuse in the fuse box, I would like to install the dual air horns just by replacing the horns under the hood so when I beep the horn it sounds the air horn, can this be possible and how, thank you

[@rogerjimenez3335]

I have the same question..

[@malcolmdcosta]

Hello, I purchased a similar horn and I thought I could use it indoors (for research purpose hahaha) using electric power. But I realized that I was wrong, because that compressor uses a lot of Amps. Would you recommend. Buying an AC to DC power supply will be very expensive. Would you be able to recommend the cheapest category of automotive battery that could run this power this horn. Thanks in advance for your suggestions.

[@Lesscoelectronics]

You'd be hard pressed to find a power supply to handle such draw and supply it that fast, Try using a battery and a smaller dc power supply to keep it full.

[@shaolin224]

Nice tutorial. Not much of an electrical person, but how what kind of wiring would I need to toggle between the air horn and factory horn while using the factory horn button on steering wheel

[@Lesscoelectronics]

+shaolin224 18 gauge will do it

[@shaolin224]

Okay thank you. I guess my question was a bit vague sorry. What I'd like to do is have a toggle switch that turns on power to the air horn when I want. And then use the same or a different switch to power the regular horn. So I can change between the two as desired. What change in wiring setup would I need that's differs from your vid. Thanks

[@305chevyboysp6]

i got wolo train horn if i unhook up to the factor horn do i need the relay

[@LordLancifer]

Is there just a single wire to your stock horn? If so, it is probably a positive wire, and the horn is grounded on the chassis. If this is the case, just plug that wire to the positive pin on the compressor, and make a second wire that runs from the negative post of the compressor to a ground point on your car (the shorter the wire the better). You can use a loop connector on the end of the negative wire to get grounded on that bolt. Just sand down the paint under the bolt head so that it contacts metal and makes a good ground connection.

[@laurenloukinen6790]

it is also good for fire trucks,ambulances , heavy rescue etc!!!!!!!!!

[@itolond]

what gauge wire for 12v system to the Compressor is best?

[@johnstoker1944]

How many decibles?

[@drewshaneyfelt]

I am running dual compressors with 4 air horns from Harbor Freight along with an inline 30 amp fuse and 40 amp 4 post relay like the one in this video (purchased from Schucks). I hooked up my power jumper wire from the battery positive+ to 30 & 86 and 85 is a ground wire ran to a momentary switch inside the truck along with 87 going to the positive+ on both of the air compressors. I was able to get a few good bursts out of the setup before the fuse blew. Where did I go wrong? Do I need to switch my battery positive from 30 to 87?

[@Lesscoelectronics]

+Andrew Shaneyfelt No, I presume you need to upgrade the circuit itself, fuse and all, Doing an amp draw test with a multimeter wouldn't be a bad idea either! and lastly upgrade the wiring if it's less than 16ga.

[@drewshaneyfelt]

+Lessco Electronics I am running 12ga wire for my grounds and power and 16ga for the switch wire. I assume that it doesnt matter which post the wires are on for 30 and 87, i.e. I can have the battery power on either of them and jumped over to post 86. Is that correct?

[@Lesscoelectronics]

You can wire the relay several ways and get the same thing, My recommendation is 85 and 86 are the coil trigger(put + and - on either side, doesnt make much diffference), I'd put constant fused 12v+ to 87 and use 30 as your output. I noticed a fatal flaw in your power wiring though, if you have 12ga on the +side and 12ga on the other YOU ESSENTIALLY HAVE A 16ga CIRCUIT! you need 12ga on both sides to have a 12ga circuit my friend. update that!

[@drewshaneyfelt]

+Lessco Electronics I finally figured out what my issue was, go figure I just needed to install a 40 amp in line fuse rather than a 30 amp and I was good to go. Thanks again for the feedback.

[@Lesscoelectronics]

welcome

[@jannes1418]

hey, can i connect wires directly to the compressor from my old horn?

[@matarazzo209]

Yes remove old horn use those wires to rewire this and you're good

[@thomaslockley945]

an how you ground it there

[@simongray7620]

bud you really need to set your camera up correctly so how of focus

[@Butterflytaxidfw]

Thank you I had thought I had installed the 3 horn harbor freight horns correctly and it worked once but, it stopped. The way i wired it was. 30 through fuse to positive, 86 i wired to the positive side of the existing horn, jumped 87 to compressor positive and the extra terminal on the compressor for tuning and then I tied 85 to ground. It stopped working after the first time I drove the car. I wonder if it would work if I unhooked the existing horns? I am not going to tear into the steering wheel of my 2016 Altima to get a horn wire., there is an airbag in there. Please advise

[@braveheart6850]

Good video. 1-How would i know if i have a negative output? Where is my horn switch under the hood? I have two horns behind the grill. Each horn has two wires. A green and red. I hooked up wires from horn to the battery just to test it. It was loud. I then used the original wires from the old horn and connected them directly to the new horn (no Relay). When i press the horn on the steering column the horn sound was 25% of what it was when I tried directly onto the battery. Any idea why? I have a 2013 Sonata Limited. I would prefer NOT to use a relay if I can get away with it. Would like to use the original wires and change the fuse to 20 amp. Since the horn is only used for short spurts, I am not concerned about the insulation burning off the wire

[@claudiopicos4137]

Donde la compro

[@BigDave12768]

Why grab signal under dash. Why not just grab signal off wire at horn?

[@Lesscoelectronics]

the wire under the dash is the input side of the horn relay, the wire at the horn is the wire on the output side of the power relay, that's why that is.

[@BigDave12768]

+Lessco Electronics yes but if snip the wire at the horns you can control the out put of the horns and have an on off switch and just use signal from horns right there.

[@Lesscoelectronics]

the issue there is that now youre limited to the factory circuits output capabilities, most upgrade kits demand 2-3x (or more) the amperage a standard stock horn supplies.

[@HoangNguyen-df2vx]

cai nay ngon day

[@jorgemorales1141]

do u NEED the relay?

[@krallopian]

You only NEED the relay to switch the high power. If you want to buy a high-power switch (they're cheap and easily available) then you can run the wire directly. The only benefit to a relay is: Switch selection is WAY better when you use a relay, you can use a decorative switch, one that lights up, etc.. AND most importantly, it's far safer. To have high power wire running through the cabin isn't as safe as a switched relay. Relays are super cheap and super easy, they're scary at first because of all of their pins, what size, what rating etc.. but really all you need is a "12v relay" with a high enough amperage rating for whatever you're using. 5amp horn? Get a 10amp 12v relay and it'll be no problem - and can cost 30¢ Hope this helps
