Works great for horn upgrade.
Works perfectly for upgrading to an aftermarket horn. Used this harness for a hella horn install and it came out excellent. Only gripe is harness should come with a few black zip ties. Worth the money for how easy the direct plug and play was. Horns sound so crisp now. Easily fits into grille after tying down with electrical tape but isn’t needed.

Perfect fit and length
24 Corolla GR horn upgrade Way more than enough length to allow you to run 2 horns on each side of the radiator support. Very clean and the plugs fit perfect into the Hella horns I chose

Durable harness
I bought this adapter for my 2006 Toyota Corolla since it only had one basic horn and it was starting to give out. I then bought a new horn kit for my Corolla and I also bought this adapter to install 2 horns instead of the 1 horn it had. This harness was very easy to install, and it took about 3 minutes or less to install the harness. I find the harness durable because of the protective wire wrap it comes installed with, and the connectors have a strong connection to the harness. I also like the look of the harness since it easily blends with the other factory wiring in the engine bay. This harness is worth the money, especially since it has a high-quality adapter and has the protective wire wrap installed. Now my Corolla sounds like a proper vehicle with 2 car horns!

Shipping took ages but it works.
Item works as intended….could use some electrical tap around the wire loom and connector…other than that…shipping took 2 decades…but eventually showed up.

lo compre para una bocina doble de hela, le quedo muy bien y hasta el momento no me ha dado ninguna falla. Lo instale en un corolla 2011, no necesite ningún adaptado
