Ok thanks man! Yea Honda gave me a hard time at first. The manager said they would only work with Honda parts. Not aftermarket. I showed them physically and the link where I bought them. They said it's not guaranteed to work lol smfh.
Horn Upgrade
Did a few searches but did not find anything on this subject so I thought I would start a thread to see if anyone has upgraded the OEM chipmunk fart horns. The OEM horns have a odd one pin waterproof connector and the only plug and play solution I found is the aftermarket "sport" horn kit sold by College Hills Honda, they have the correct connectors built in and are only $15 on their website, but I wanted something louder. They also sell a wiring adapter kit that allows use of aftermarket horns with the more common spade connectors. The real limitation is in the stock wiring is that it is very thin gauge and the 10 amp horn circuit capacity. Most twin horn kits draw more than the stock circuit can handle and require a relay and higher amperage fused circuit from the battery. You can access the drivers side (left) horn from above but the passenger side (right) horn is mounted low and may require removal of the inner wheel well. I decided to use the wiring adapter lead that plugs into the OEM connector to trigger a relay for new 20 amp horn circuit using 12 gauge wire and 20A fuse holder directly to the battery. I used the accessible left side horn wire for the relay trigger and installed a Stebel Nautilus compact air horn at the left horn location. The right side horn was not touched because it was too hard to get to, and on my LX it is the horn that "chirps" when I double press my keyfob lock button. The results? Well, distracted half awake commuters will no longer ignore the polite "meep" from the stock horns as they drift into my lane, this thing will get anyone's attention, even with windows up and radio on! The pic below shows the main components but not the 12 gauge connecting wire.

This is the one that I bought. The listing is for OEM but I don’t see anything that would confirm that. I understand what you mean about other companies making parts for the car manufacturer (like Delco for GM cars and Bosch for European cars for example). I can’t look up the part number for my car because these are Accord horns to change the sound from “beep” to “honk”. I may have gotten the eBay listing from this thread but don’t remember.

This, quoted, is where I got the information to use the 2007 Honda Accord horns. I have requested a return/refund on the fake “OEM” horns and will get some authentic either online or at the dealership.Mostly my wife drives our HRV but I ran an errand in it the other day and I needed the horn...siiiighhh...
I was working on our Acura TSX and noticed the horns on it. Took one off and plugged it into the HRV with a ground jumper wire.
The connector is identical, the horn is just much larger and much louder.
A quick cross-reference of Honda p/ns and found that the 2006 TSX horns are also used in the 2000-07 Honda Accords.
Off to a self-serve auto-wrecker, tons of Accords, picked up 2 horns off an '07 Accord, pass and drivers side, high and low frequency.
They look identical to the pics in this thread.
Back home, tested both horns with a 12V test power supply, took about an hour to install both in the HRV, plug and play.
Broke all 3 plastic pin retainers on the passenger side underbody front access panel.
The pin retainers are different than the other underbody pins.
I have tons of various Honda pins, clips, etc. You always need those on hand when working on a Honda.
Replaced those pins and installed both horns. Low frequency on the drivers side and high freq on the pass side.
It likely doesn't matter which side is which anyway.
And now our HRV has real horns for a total of CDN$5/ US$3.75 and a couple hours of quality time in the garage!
Thanks to everyone for the info in this thread...
No disrespect, but you are over-thinking these 2 simple horns!
I did install 2 OEM Honda Accord horns in our HRV but they were 12+ years old, used and US$3.75 for both.
My goal was to upgrade our HRV horns as simply and cheaply as possible.
The opposite of the battery upgrade in our HRV!
No issues at all with our HRV horn upgrade 2 years ago. I had forgotten all about it.
No issues with our battery upgrade 2 years ago either!
