Air Horn Car Install and Relay Wiring Instructions

[@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 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

[@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.

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!

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

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

How much amperage is that horn pulling? Those are some mighty thick wires you have there. Look like maybe 10awg. I'm prolly wrong. Great video man. Very sharp, clear audio and good camera work.

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.

[@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.

One stays on the horn, the other goes to your relay.

[@mardis123]

Great video! Where can I get that harness that plugs into the relay?

[@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?

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?

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

[@alchance662]

My goal is to cut out the OEM horns from blowing at all, and using original relay circuit to install Air Horn in place of OEM Horns. I want to blow the Air horns via existing stock steering wheel center button. My OEM Horns are only accessible by removing the Bumper. I do not want to do that. Assuming I can locate those wires (to the OEM Horns), and isolate them from the circuit, I understand I must use a rated Fuse for the Air Horn (due to greater current draw). Is it as easy as replacing that OEM Fuse with the larger rated one, or is there more to be concerned with here - like gauge of OEM wires being used for OEM Horns, now to carry the load for Air Horns?

I have a question. Is the original power wire for the original horn heavy enough gage to carry the current? You ran a new wire to the battery, why? Cant you just install the relay into the original wires to the horn is my real question?

[@StrangeGarage]

Original horn only draws a few amps of power, so horn relay and fuse will not be able to run the compressor for the new horn, which draws 20-25 amps peak. That's why I installed another relay and an in-line fuse.

[@brewingman56]

@@StrangeGarage Thanks, yes, I understand the adding of the fuse and rely, but is the wiring heavy enough to handle the increase in amperage without installing new wiring.

[@StrangeGarage]

@@brewingman56 The existing power cannot supply it. The remote relay circumvents that. If you can wire it without using the battery, be my guest. But all wires in that vehicle go through the fuse box (IE are already restricted in amperage). The battery is where you get unrestricted power, and the fuse you install regulates it. I'm sorry if this doesn't make sense, but installing the relay makes factory wiring obsolete.
