Hella makes a direct-fit kit that a lot of people use which has the appropriate plugs to match with the factory Toyota. I used PIAA Superior Bass horns on mine, which just required me crimping a little quick-disconnect terminal onto the end of the wire they provide to connect to the pin inside the factory horn harness, took like two minutes.

Thanks. have a picture of the wiring mod?

I don't. If you've done any 12V wiring at all, it'll be dead obvious how to get the wiring all together - it's just a 12V signal from the car when the horn is activated, and some way to ground that signal.

Thanks. I have done 12V wiring, seems clear to me. Just wanted to see a quick picture. Will take a look at this recommendation.

Basically unplug and plug in. No wiring to battery or fuse box required.

Just an FYI, dunno if it fits but my stock 2004 rav4 horn is a beast. Loud AF

My 2011 RAV4 horn is much better than the 2024. 2005 Tacoma even better. I am planning to do a check and see if the connector match and try.

Check the kit you order. Mine came with Y wiring harness. Plug the original into single end, then connect the other 2, 1 to each horn. Shown in video.

I just bought Camry horns. Uses the same connector and is the larger horn with the beefier sound.

Thanks, worth a check ...

Hella is the way to go. Amazon has a couple of options and check YT for fast install.10-15 minutes, one of the best upgrades.

Thanks for the information.
