Swapped out my stock 2015 Subaru horns for these. Ran them off of a relay. Sound exactly the same. The horns are big and beefy, but it's all show and no go. Either that or the stock Subaru horns are actually pretty decent. I'd only do this if you are repairing failed horn(s). If you think these will be an upgrade, I think you'll be disappointed. I don't think electric horns like these have any polarity. It's a simple circuit. One is power, the other is ground, but it doesn't matter which.

[@PBS-nm1uu]

this was a good video, the wiring of the horn is the most important part, thanks

[@Vito_993]

Me: thinking it was plug and play lol

[@rickj13]

10:27 of my life gone, only to find out you didn’t bother wiring the relay or directly to the battery. That is what I wanted to see. Anyone can plug stock terminals to new horns.

We currently do not have an auto repair video that covers this particular repair. We will keep this request in mind in the event that we need to make this repair in the future. 1aauto.com +rickj13

You dont need a relay if you replace the oem horns.

[@Samlol23_drrich]

Well done. Only video I've seen where someone worked the penetrant in

[@theeprodigalson]

10 minutes in to "how to wire your horn" and you never show us how to wire the horn. Thanks

[@chillozz1]

that white circular thing... Is that for adjusting the loudness of the horn??? I have olso a hella horn but that part i cant turn... and there is a turn indication sign...

[@emanuel686]

I just bought a box of Sharp tones and there's a bold warning on it that says: Do not adjust the position (angle) of the bracket or the nut. It changes the electromechanical properties and will result in loss of performance and warranty. Isn't that what you suggested to do in the video? Also, why not using the relay that's included in the box?

[@AlexTurbo]

I’m wondering the same thing… my box has that same warning in bold font

[@Hallowsaw]

Where did the first positive wire come from cause the secon one you said was from the original harness

[@MrMasterFlash]

How can you tell which is positive and wich is negative?

[@Chris-fj9ir]

Did you run tbe ground from horn to horn. Or ground to frame? Inreally need more detail, im not that smart

[@vrush_sane17]

No relay required?

[@GroovesAndLands]

Not "required" but if you don't, you'll likely cook the OEM relay if you lay on the horns for awhile. The Hellas pull 15A each! Additionally, because of the large current draw, their will be a voltage drop if you use the skinny OEM wiring, and the horns won't be as loud as they otherwise would.

[@fuerzademapuche2532]

@@GroovesAndLands Sir, or Ma'am....thank you, I learned way more from just reading your comment than from watching almost 20 videos on installing dual horns from the original 1 horn setup. It has been frustrating to say the least, but now I understand better, all because of you. Thank you!

[@richmalt574]

I have the same one and they don’t have polarity

[@thehegt]

So install the L tone on the driver side and high tone on passenger?

[@kotastrophie]

Nowadays a plus sign can be and look however it wants to don’t judge it on how it looks

[@Vito_993]

What’s the point people put a relay and all?

[@atifzaidi8198]

Hella Horns Are Made In India Now😍I Too Have Same Pair In My Kawasaki Bike.

[@krisk1547]

yea the warranty on it says 6 months or 9 months from date of manufacturing . So warranty is gone by the time is sold :P

how to wire ?????

[@DARREN_STI_WANG]

Im using these horns too and i find them soft. Will the relays make them louder?

[@davidg9997]

DARREN WANG yes. You should also wire the hot side of the horns directly to the battery with a good 10 gauge wire. Using the relay in conjunction with the stock wiring will allow everything to work normally. There’s a very good right up on the Tacoma forums out there. Google is your friend.

[@kCI251]

You'd think Hella would label the power terminals, it's not that hard.

[@jakehughes8224]

What about the relay? Do you need it or not

[@aasberg]

Probably, since it pulls atleast 6 amps :) i would do it.

[@DARREN_STI_WANG]

Do the relays make them louder? I find mine too soft.

[@albowrx]

Do the relays guys, and run wire directly from the battery, pos and ground. That's the whole point of running a relay anyways, but just making sure you do it right.

[@jimcooper3048]

@@albowrx Nobody, including the Hella website or the horn package tells you WHAT to do with the relay or HOW to install it... swap out the OEM relay by just 'plug and play' ?

[@67L48]

I used a relay. Run a 12 ga power wire from the battery + to 30. Run 87 to the two horns (you'll obviously have to break this into two leads for the two horns). Run your stock horn power lead to 85 (or 86) and run 86 (or 85) to a ground point. Done. When you push your horn button (middle of steering wheel), it sends power to the relay and closes it ... that connect your battery directly to the new horns. Easy peasy japaneasy. (If you have a 5-way relay, ignore 87a ... leave it unconnected. If you don't know what these numbers are, then you probably shouldn't be doing a wiring project). Even off of a relay, these basically sound the same as my factory 2015 Subaru horns did. So, I'd not recommend this as an upgrade.

[@stevenbeatty3872]

These are going on my Elantra lol

[@codenamemamba1277]

Can you get away with 16 guage wire???

[@jeffcarroll4219]

Why didn’t you show how to wire these horns? lol Or even an explanation for the harness you created? This is not very informative. Geez

Use this to be instantly pulled over by a crazy guy with a gun 👍
