How would I go about replacing the horn wiring harness and horn

[Anthony Savage]

So my horn stopped working and I found out the wires connected to the horn was ripped out. I purchase these two items hoping to install a new horn by myself.

I bought the horn wiring because the wires were ripped off the stock horn. My question is how would I go about installing this and where is the horn relay? Here is a picture of the relay box in my 2010 Corolla.

As far as where the relay goes it should be printed on the underside of the lid of the fuse box and in the owners manual. I will not attempt to answer how to wire it in as I am not an expert.

Agree look on the cover. its Mirrored black on black lettering, not a fan of any lettering like that at all.

If I were to re-wire I would also like the original harness? I can easily get away wit ha wire, splice and heat shrink and make up the parts needed

Thanks for the feedback guys. I held off on installing it so far because of my school and work schedule but I’ll update you guys if I ever get to it lol

I replaced my car horn on the 2014 with an aooga horn a few years ago . But that was just a matter of pulling the wires off the original horn and hooking up to the new horn and mounting the horn holder up.

Oh my God, who would want to cut off the back of the wiring harness? What purpose did this man have in mind? Well, that's very silly. I've never had a problem finding vehicle wiring diagrams. Sometimes there is indeed no information there about exactly which wires do what. But always be careful when working with wiring diagrams. Electronics don't tolerate mistakes. Mistakes can cause the circuit not to work or, in the worst cases, damage parts of the circuit. Aluminum wiring mitigation is a common occurrence in these cases. So make sure you know what you're doing or enlist the help of an electrician before you get started. I know good ones here https://www.tidalelectricalservices.com/service/aluminum-wiring-mitigation/. They helped me with my house wiring, but they can also help you with your car.
