Don't change the fuse? Okay. May I ask why? I'm new to this type of modification. Will I be able to wire up the high and low horn on the existing fuse?
The size of the fuse is based on the ability of the wire to pass current without catching on fire. The fuse is designed to blow first and stop the overload process. If you just replace it with a larger one; the wires may burn.

Thanks for this diagram!!!

Going to buy parts this weekend, and wire this up.
For what it's worth, I installed a paid of Wolo Maxi 320-2T horns in my civic, and their website says that the set draws 7A (I think the horn factory fuse is 10A or so). I was eyeing the crap out of hella sharptones or supertones, but personally didn't like how it sounded. They were like $25 after tax at Pep boys

A set of Hella horns draw over 10A, I personally don't feel comfortable wiring them directly to the factory horn. Use the OE harness to trigger a relay, and wire the horns directly to the battery with a 15A fuse.

My 2020 Civics' horn sucks. Has anyone ever upgraded their horn?
I'm willing to bet no one has upgraded.
Is that sarcasm? If not, I'll take that bet!!! 🤑

I'd love a train horn.

I went Hella. If anyone knows how to add a custom "bruh" lmk! I want to "bruh" people after they sit on a green or fully stop on a yield LOL

I've got this all built out and just need to install it (just 1 courtesy horn tho). The audio file could be changed to say or sound like anything you want.

I went with different horns, but still a dual horn setup. Here's how I wired mine. Been running since August 2019 with no issues

Was getting ready to head out and buy parts based on the wiring diagram. For some reason, I decided to take one last look at the Hella horns that I bought (Hella Twin Tone Trumpet, TC16S-LT, TC16S-HT).

Each has a "OE Style" connector (per the wording box) box with one male connector. Hopefully, the picture is clarifies what I'm trying to describe.

OE horn has a pair of wires (like you show, green black). Any suggestions as to how should I run the wires to these horns?

Sorry for such a question, I'm really lousy with electrical stuff.

You might have to source male OEM connectors (or find tiny female spade connectors that fit that pin) that fit on that, then splice them into an adapter (or cut factory wiring) for the OEM horn connector. My aftermarket horn came with male spade connectors on them

That single pin would be the "+" while the metal bracket is very much likely your "-"
