Toyota RAV4 Limited V6 2007: Upgrading the Horn
I was unhappy with the stock horn on the RAV4 and decided to replace it with something a little louder and more noticeable. This was a relatively easy procedure overall. It took me about 2 hours to complete but a capable person should be able to do it within an hour.
Tools and Parts
- New Horns
- 3/8″ Socket Wrench and 14mm socket (TODO) for disconnecting radiator supports

Push the radiator torward the rear of the car and look for the horns. You will unscrew the thin nut from the back of the horn.
Disconnect electrical connector by pushing on the tab (left side of this picture)
This unit comes with an adapter for the existing electrical connector. You will connect the adapter to the existing harness on the vehicle and then you’ll have the necessary connector for the new horns. New horn requires a jumper for the ground. I connected the ground to the mounting post.
Connect up the wires and work the horn into place. I had to put the horn in backwards initially and then rotate it once I got past the lip. Curse as needed.
Attach the nut and tighten. I put the face of the horn so it was somewhat facing down. I read somewhere that this was a recommendation so it doesn’t collect water. Not sure it that’s really a problem, but I still wanted the horn to face out to the side somewhat so the dumbass I’m beeping at can hear me.
New horns installed, give them a try and then close it all up.
Move radiator back into position
Install D/P bolts
