- Thanks for watching! Let me know if you have any questions and apologies for the rolling flicket in the first shot.
I missed it in the video, but I'd also recommend adding a fuse between the +12V source and the relay for additional safety.

For anyone that buys Hella horns that don’t come with a relay, get the Bosch 4 pin relay from amazon or whatever the fuk.

miata tip: avoid pushing your hood closed. They're made of soft aluminum and can bend and warp even from a little pressure. It's best to just give it a good enough drop that gravity completely latches it closed.
can personally attest, my hood is bent on the passenger side near the windshield from this
Gotta love the maker mentality on full display. Got an understanding of the principles behind the horn, drew up the plan, and set things up, THEN realized there were instructions.
If I’m not mistaken the hella horns work off 12v the same as factory, so you could have eliminated the relay and the extra harness you made if you just connected it directly to the factory wiring harness since it’s already fused and has a relay dedicated for it. & Yes you would have still had to cut and put on new terminal maybe even had to extend the wires but that’s only 2 connections vs the 4 + the extra relay in the circuit regardless it’s just for a future heads up. Still nice work 👍🏾
Thanks. Of all the videos on CZcams on these horns yours is the most detailed and useful.
Thanks! Just got done installing these in my 2002 LS. Liked your tip on using an OEM horn bracket for the additional horn unit, so managed to find a salvage one. Got tripped up by the relay diagram, so came back here for a sanity check. I was doing new headlight shells, so figured while the front bumper cover was off, why not tackle the horn upgrade? Can't wait to scare people with these!
If only I saw this video last year.
My two Hellas are quiet because I didn't want to mess up anything by running wires to the battery and fry something.
Thanks!
Great video , installed some truck horns from the junk yard and this video helped a lot
Thank you so much for this guide. I would have figured it out eventually but you made it painless!
This channel is pretty cool lol I have owned a 2004 silver nb for almost 2 years now and am now looking to buy a mazda 3.
Loved it man! That horn does sound way better! Found my way here via Facebook!
You've got my sub. Great video. Keep it up man!
THanks for posting, i've got my new Hella horns, but a different style, Euro tuned, I think. But they do not come across as load on the video. Just a little beep, not much louder at all. I replaced the horns on my Alfa Romeo and on my Triumph Rocket, so normally the difference is quite a bit.
But perhaps it did not come through. A shame I have to remove the front bumper cover!!!!!
I’m thinking of getting these horns for my nb se, just had case of someone not even noticing me honking when they were backing out into me. I’m new to this stuff and see people are talking about fuses, where would you put it in this mod? Would you replace the 15amp fuse already in the fuse box for the OEM horn with a 20amp one, or put an inline fuse somewhere else in the circuit, like on the wire going to the 12v bolt or on the OEM horn wire?
Just continuation, but it seems like you’d need a fuse between the bolt and relay, would you also need one between relay and OEM tap? Sorry if this sounds stupid, I’d rather not cause any serious damage to other systems.
I put one inline between the fuse box and relay, as close to the fuse box as you can. You shouldn't need to add a fuse to the OEM tap as it's pulling very low current and already fused (OEM horn shares fuse with brake lights)
Okay great, thank you so much!
Using the oem horn brackets with these horns pressed both against AC piping behind the humper. Did you do anything to try and modify the brackets?
Is the relay necessary? Can you just splice the factory horn wire and go to the second horn since the use is intermittent. And they are already wired in parallel.
It doesn't look like there is a fuse protecting the new horn.
no I went back and added one right after filming the video because I realized I had forgotten
Where would you put the fuse? I’m guessing between 12v bolt and relay, but do you need one between relay and OEM relay (I’m guessing that’s where that OEM wire goes)? Sorry if that’s a stupid question lmao.
can i ask where you added the fuse and what type of fuse was added? your video is literally the onluy useful video i found, i just needa know where that fuse went and if you needed another relay for safety?@@halomakes
It seemed like you got a 2ed horn bracket, but you didn't say from where, I don't think!! And why couldn't both the horns not be put in like you did the 2ed one???
Link for the horn bracket is in the video description. You probably could put both horns in that way but wiring would be a little more difficult. I was going off of what I'd read online so I didn't have the power of retrospect on my side.
Nice install bro , I agree there horn is low low on the Miata
Great vid, thanks gonna be doing this soon. Question: where did you get the hood prop for the car?
That was the cobalt one from moss. I have since switched to the flyin Miata ones
2 questions
1: what gauge wire should I use?
2: where would said fuse be placed and how? Does it take the place of an existing fuse or is it an extra one placed in the fuse box?
Also did you wire up the 300hz or 500hz horn first? Does it matter?
I think I used 16 gauge, that should be plenty.
Use an inline fuse, put as close to the power source as you realistically can smile.amazon.com/dp/B081DHT8Y7/ref=cm_sw_r_apan_glt_i_H12ZZQBKJVFMZYYEG1VT
Doesn't matter which order, they are wired in parallel
@@halomakes thanks a ton brother! I went with 14 gauge wire and an in-line fuse, you helped me out big time with this video!
@@halomakes what size fuse did you use in the inline slot?
Hey man, I have one more question. I just wired my horns up and they aren’t working. I’m using the original horn wire that went from the factory relay and wired it into the new relay, the new relay is clicking but isn’t sending power to the horns, what could be causing this? Could it be going through the old relay that causes this?
Maybe your horns aren't properly grounded
@@halomakes I triple checked the relay ground, but not the horn grounds, thanks for the idea.
I want to install as loud of a horn I can get for my miata thats legal, any ideas anyone? I just want my 97 miata to definitely be seen when ppl pull out, back up real close, etc
Your headlights look sicc man! Can you link me to where I got them?
They are spec-d tuning lights. www.ebay.com/itm/381537314280
The actual light pattern isn't great, I would recommend just cleaning up your stock ones.
Wait a minute your nb2 had hood struts?!
