DIY Horn replacement on F32
So my horns turned into clown horn couple weeks ago, I ordered universal horns both low / high tone on amazon and put them in today. All youtube video showed the process with the wheels taken off, I'm too lazy so I did it with the wheels on. Ample room actually. First I have to apologize, the pictures are kinda crappy coz it was a pain in the ass to work on to begin with, so I forgot to take more pics in the process but I'll list the process below:
Step 1: Take your new horns, and strip some wires, crimp it to new connectors, insert it on the new horns terminals and pull for tightness test. (pic 1) Step 2: Turn on the car, and turn your wheels fully locked to one side. I found when the wheels are facing outward, there's more room than facing inward. Step 3: Disconnect negative terminal on battery. Because I'm not using the cheap flimsy OEM horns, the connections have to be cut and rewired, so to avoid shorting out the battery while cutting wires, I just disconnect it to be safe. Step 4: There's about ten 8mm screws on the front flap to take off, they are in front of the wheel, can't miss em. (pic 3) Step 5: you need to take off a 1/2" nut securing the horn on the bracket. Don't drop the socket, I did and it some how rolled to the middle inside the bumper, what a pain in the ass to get that out, then unplug the OEM connector by pressing the top locking mechanism and pull. (pic 2) Step 6: Look at how cheap and tiny the OEM horns are, no wonder they only last 3 years (pic 4 & 5) Step 7: Cut the wires just behind the OEM plug and strip to about 1.5 cm, use twist on electrical marrets to tie the wires from the new horn onto the stock wires, you can pick which wires to connect, it doesn't matter because there is no voltage polarity for the horn. Step 8: Cover all exposed terminals with electrical tape on the new horn, mount the new horn, tighten the 1/2" bracket nut, my new horns were quite a bit bigger than the stock ones, so I had to bend the bracket slightly for fitment, you may need to do that too, the bracket can be bent by hand, no tools required, then tighten all 8mm screws back for the front cover. Repeat on the other front wheel. Stock low tone horn is on the left front wheel and high tone is on the right front wheel (when looking forward inside the car) My wife says the horn is too loud now, well, it's not for her anyway.

no need for jack stands in this case because you would not be under the car |

Unless you have one of these at home, it's going to be slightly longer than 5 seconds to remove a wheel.
But seriously, doesn't matter which wire connects to the brown one? I had Hella Super Tones on my old subaru and I'm considering it for the F30.

But yes, it doesn't matter which wire connects to the brown, for my low and high tone horns, I purposely connected opposite terminals to brown just to confirm. It made no difference, both horns now super loud. If your Hella horns has a + and - label on the terminals, then I would still put the positive to the half white half blue and negative to brown, just to do what its shown, otherwise it shouldn't matter.

I replaced both horns on my car few days ago. It's really easy job. The only thing is that horns are really expensive. $200 for both at the dealership here in Chicago. At the dealership they wanted to charge me at least 2 hrs of labor, which comes $360. Good thing I've done it myself

what do you mean? I know battery needs to be registered with ecu after replacement, never heard of registering horns. They work perfectly right now, I used it on a sleeping right turn women yesterday, people from half a block away looked back, loud as it gets

The connector from the old horn does look like it might fit the new? But no idea how the old can be removed, it does look like it’s rivetted so if you could get it off you might be able to solder it to the new.

Any idea of the easiest and cleanest way to install on the F30? https://www.amazon.com/150DB-Super-T.../dp/B07L9LPF78 |
