Quick OEM PNP Horn Upgrade:

I have never been happy with my H3's extremely dull/low sounding horn. I replaced it with one out of a Ford Ranger, and it was better, but I just found another completely OEM and quick PNP upgrade. It's the OEM stock dual horn setup from a 2014 Nissan Frontier. Was looking under the hood of one and noticed it had the same style OEM plug, but then it's got an extra set of leads going to another horn!! It gives you a H note horn & a L note horn. All you have to do is take a flat piece of steel and make an additional mount for horn #2. Took me maybe 10-15min from start to finish.

The sound is NIGHT/DAY!!! I ended up using a 5inch piece of flat steel, drilling a hole at each end for the horns, and then drilled a hole in the middle for the OEM single mount to attach to the flat steel. Not sure of what the actual cost of the horns are. I have a friend that works at the local Nissan/Honda dealership and he scored me a set. Very happy now with the results and it looks completely OEM without having to rewire anything!

This mod is a must! Try and post a vid with the sound.

Yeah I tried to post a video of the sound lol. It made my phone just sound like BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBeeeeeeeeeeeeep! It's even a huge improvement on just using the remote! Before I had to always check and make sure it was actually locked since I couldn't go by the sound of the horn.

When I bought my H3 used I thought the horn was bad because it sounded so weak. Bought a unit for an 08 Ford Ranger (once again OEM PNP compatible) and it was better, but I always wanted more. I was hanging out with my Nissan friend, and he was showing me under the hood of a 2014 with the 4.0L V6 (I used to have an 01 4x4 Xterra SE with the 3.3L V6). While snooping around I noticed the horn config down behind the LF headlight and I inspected it closer. I told my buddy that setup would be perfect in my H3, and he said he'd check and see if any where laying around since that setup has been around for years (think since 05). Well he somehow scored me a brand new set for nothing. I just wanted to post this info/mod up for anyone wanting a louder OEM PNP setup vs hacking the OEM wiring or serious mods.

I installed a $30 "Bad Boy" horn from O'Reilly's on my old H3 without any wiring change. The rated load was higher but it never blew the fuse. IIRC, I just put it on the same bracket as the OEM horn. A real air horn rig in the T would be cool, but $$$.

All the horns I saw at Auto Zone/Advance/Oreilly's, but none of them had the OEM Plug our H3's had. Jeep/Ford/Nissan and I'm sure several others do. That's why I went that route vs those horns at the parts store

Nice to know that there is some commanaliity with the plugs for those that are not confident working with wires. Thanks for sharing!

For those that are contemplating getting an air horn, think "on-board air". Easy to justify if you are goinf to buy a compressor for airing-up after a trail anyways.

The compact Wolo air horns are worth their money as well. The Bad Boy horn has a higher pitch, making it sound like a smaller car. The Big Bad Max horn is basically the same as the Bad Boy but with a lower pitch. I put one on the Kia Soul and just love it!
