Air Train Horn Wiring Circuit - Part 3

*Part 3 of 3 series*
If you want to be heard then an air horn is the way to go. Some folks call it a train horn but one thing is for sure they are loud! This video demonstrates how to the wiring is connected on an air train horn. This is part one of three part series and goes into depth on how to wire the horn air compressor and horn solenoid with an in dash switch.

Can't tell you how much trouble I was having hooking my horn up. Your separate circuit explanation cleared everything up ! Thanks so much !

[@ozzstars_cars]

Glad it helped Norman.

[@mattmaresca7647]

We just installed a hornblaster kit on my sons’ 2019 Ford 150 and couldn’t have done it correctly the first time without your whiteboard diagram! Super helpful! You’re absolutely right with regard to time to completion. Took us two days not a few hours and the lack of directions/guidance that were provided by Hornblasters was very disappointing. Thank you again my friend!

Fantastic video, explaining it made it so easy for install. Could I just tap into the factory horn and install a cut off switch

[@gunsmoke_code3882]

Great 👍 Do you have a diagram of tapping in to the factory horns with a switch so I can choose from air horns and factory horns

[@tonystricker6672]

Great Video! I was thinking of running the compressor to the 30amp up-fitter switch on my Raptor instead of the fuse box. Would that work to control the power to the compressor, and then when that is on, the button on the horn side would then be allowed to sound the horns? Interested in your thoughts! Thanks!

[@tomnutt6022]

Excellent drawing and explanation... Einstein has nothing on you bro

[@ozzstars_cars]

Haha! Tom are you saying I discovered the Theory of Train Horn Relativity?

[@sixtyfiveford]

That'll get some attention.

[@caleschulz5019]

Could I add a inline on/off switch after the 5A fuse at the power distribution block and before the pressure switch? That way the the compressor will only kick on if the ignition is on and the switch is on. Thank you so much. This video explains this better than anyone else.

[@traebagley4387]

Wired up a train horn on my dually service truck last year. Being a plumber I can follow a diagram but had no idea how it worked. Quit working on me last week. Got mad trouble shooting and snatched all the wiring out. Good news is this video gave me the full picture and knowledge to get it back functioning properly. Bad news is I should’ve watched it before snatching it all out… now that I know what’s going on I either had a bad ground or my pressure switch failed. I’m going to say the switch failed to save me from the embarrassment of a bad ground wire being the cause. Thank you for the information.

[@ozzstars_cars]

Glad the video was helpful to you Trae?

[@brentloftin5099]

What air compressor did y’all use I’ve been looking for a good one

[@SmittySmithsonite]

Great stuff, man! Nice work with the White Board of Knowledge! If I ever get a white board, I'll call it, The White Board of DOOOOM, then throw on some heavy metal music ... just because that picture in my head makes me laugh a bit. :D I already told you about my S15 air horns, but I got that idea from my dad. He put a set of Euro air horns (high pitched) under the hood of his '84 Ramcharger. One day we were coming back from my grandma's place right on the edge of the city, and this guy was standing out in the road shoveling the snowbank in front of his driveway. My dad let 'er rip, and the shovel went airborne, and the guy went down! My dad was roaring! That guy wasn't too happy with us, HAHAHAHA! MA life! I installed my compressors in the Silverado with a switch as well. When I was looking at the supplied wiring diagram and seeing only the pressure switch controlling the circuit, I knew that wouldn't fly. I put a switch in the cab, between my legs under the dash. Biggest problem is, the compressor shuts off, then I forget and leave the switch on! I've flattened the battery a few times over the past 7 years as the thing cycled all night long. I've tried to fix every leak in the system, but now I've got so many air lines between the air bags, in-cab air bag controller, and the Ox Locker, that I have a million leak points. It only leaks in cold weather. In the summer, the pressure gauge will stay put for a month. The colder it is, the faster it leaks. Can't spray anything in these temps because it freezes almost instantly. Fire up the Face Melter and warm the shop up, the leaks stop! It's infuriating. I have to keep hitting the air switch to keep the bags minimally inflated. 1st world problems, lol. Life has been much worse! :)

[@ozzstars_cars]

Great story there Smitty! Air leaks and squeaks, the two most annoying things a car (or truck) can have.

[@SteveRobReviews]

Nice explanation Glen , buddy is some good looking eh 😅😅

[@ozzstars_cars]

Sure is, haha Thanks Steve

[@brentloftin5099]

Oh and what gauge wire was the other wire

[@jfinch4676]

I’ve had issues with my switch. I have a momentary switch wired up on the positive side and every time I hit the button the truck dies. I’m grounded from the solenoid right to frame and positive to battery, with only the fuse and switch. Can’t figure out why it does that, any help???

[@brutedevotee6750]

What if the pressure and compressor were connected together do I cut it and do it separately like your diagram? It comes hooked up together from the manufacture

[@jpascaln]

It is simpler if they are wired together. You dont need a relay. Just conect the hot to ignition on power and your compressor runs independent maintaining max pressure at all times. Connect the horn silinoid to you horn button.

[@MontanaFree]

Is there any reason why I should connect the horn button/momentary switch directly to the battery as opposed to getting power from the fuse panel? I don't really want to run another wire when I have a fuse panel near the button. Thanks!!

[@ozzstars_cars]

That works, make sure it is the correct amperage or you might let the magic smoke out.

[@jacobschrenk6946]

So can i put a switch in the 86 wire to control the pump when the vehicle is on?

[@ozzstars_cars]

The white board of knowledge.

[@MontanaFree]

Does the solenoid need to be mounted to the horn or can you mount it in the tank and run an air line with fittings to the horn? I have a fitment issue. Thanks!

[@ozzstars_cars]

The horn installed in the video has it's own solenoid built in. If it is not energized air will not flow through to operate. What is your specific fitment issue?

[@MontanaFree]

@@ozzstars_cars Hi thanks. My setup has a separate solenoid. I found out it’s ok to have it directly to the tank and run an air line to the horns. I appreciate you getting back to me!

[@jacrispy8802]

On my unit the pressure sensor is wired into the compressor already, so could I run power straight from the battery, to a switch, to the 86 port and it would essentially work the same? Rather than it run on keyed power, it runs when the switch is turned on?

[@gerardosegundo6068]

Did you figure it out and how did you use the relay

[@edwindominguez2548]

I recently bought a horn kit but didnt include the relay what way could i wire it

[@ozzstars_cars]

The correct way works best.

So is it possible to just run it all the time hot without the relay or ignition source and just put a switch after the fuse to turn compressor on and off without using the pressure switch?

You might have a short somewhere. It's almost impossible to diagnose over the internet. Hope you figure it out.

Mine also. I would assume the pressure switch is built in with the two leads. But I'm having the same issue lol.

[@therealeinstein]

You have to wire the pressure switch to a relay that provides power to the compressor all of your 12/24 volt compressors only have 2 wires

[@heavyflippingrandmasboifir669]

My tank has only two wires…the pressure switch is connected to the tank….my question is where does my switch go & what pin on the relay do I tap into using a 5 pin relay? Thank you in advance.

Did.you watch the entire 3 part series?

[@dancarlosbacalso7040]

Could I use a switch instead of the power distribution box?

[@ozzstars_cars]

Switches don't provide power, they interrupt power and ground.

[@dancarlosbacalso7040]

Sorry, I mean like a switch connected to 12v

[@dancarlosbacalso7040]

Or could I use the remote turn on from my head unit since I have an amplifier installed?

[@enriquenunez7784]

Kind of threw me off. Not a lot. But for pressure switch there both hot 12v. Correct? I got confused when you mentioned 86 needs a ground. But it’s all hot..? Sorry confused a bit.

I suggest you rewatch the video and take notes to get a better understanding. The pressure switch is wired hot .

There is no horn switch for the compressor circuit. You may want to watch the left diagram discussion again.

The second diagram is wrong.

[@jacobtaylor2212]

I wired my relay up exactly the same and did my pressure switch the same exact way and my compressor is not kicking on the only thing I did different was ran my relay ground to the battery

The "compressor circuit" diagram image on the right, didn't show where a push Button would be placed. Or did i miss something?!

Why would you need a button to turn on the compressor when it is wired with a pressure switch to turn it on and off automatically?

[@jpascaln]

​@@ozzstars_cars He is asking about a horn button. Why would you need a relay to work a pressure switch. Just wire the pressure switch directly to ignition on power and ground. It will run independent of anything else. Then run a horn button to the horn solenoid. You dont need a relay at all.
