I have decided to change the horn on my 2020 Toyota Rav4 Hybrid Limited Edition. Although the Toyota horn is a traditional sound, I wanted something louder. Remove the faceplate, access the horns and disconnect the existing horn wiring harness from the stock horns. The first thing I noticed is that you need to adjust the position of the Hella horn so that the existing wiring harness reaches to the connector. There is a black screw that you loosen to turn the Hella horn to adjust the position for the connector. Once you are comfortable in the horn position, tighten the black screw and install the horn. Plug in the horn harness and you're good to go. These Hella horns sound a lot better than the standard, traditional Toyota "meep-meep" horns. This horn will attract the attention of any driver or pedestrian. It's very easy to change and it's plug and play. Thanks for your time. Much luck. If you have any questions, please post them here.
