Items needed
Aftermarket horns
12mm socket and wrench
10mm socket
Horn adapter harness
Horn harness
Zip ties
Remove the front bumper. There are multiple walk through on this forum and youtube so I won't bore you with the steps but I will provide some helpful tips. Removing the side markers will make the bumper removal easier. This bumper is held in by tabs that are going in opposite directions so the tabs need to be pressed down to remove the bumper. Do not pull blindly on the bumper or something will break. Go to home depot and get a free metal paint can tool from the paint department. This thing is perfect for removing the pushpins in one quick motion.
Disconnect the battery
Use a 12mm wrench to remove the horn bracket from the vehicle
Use a 12mm socket or wrench to remove the horn from the bracket
There are different setups for installing the horn. I used the original mounting point for one of the horns. I used the spot where the horn bracket attaches to the vehicle. Have the back of the horns with the terminals face backwards as the opening in the grill will cause water to come in
Now, you can cut the original oem wiring and just splice additional wires to the positive and negative terminals on each horn and it would work. I decided I wanted the process to be as plug and play as possible. I purchased a horn adapter from Collegehillshonda for $8. After reading the forums about adding a horn, I decided to add a harness with a relay to not damage the original wire and to prevent blowing a fuse. I purchased a horn wires harness from eBay for $4. It's a universal harness and fit perfectly for put car. Here's some photos and a diagram
Plug the horn adapter harness to the female oem connector
Attach the horn adapter harness to the eBay horn harness
Take a positive wire from the horn harness and attach it to a metal terminal on each of the horns. The horns are polar positive so it does not matter which side you connect them to as long as each horn has a positive and negative connection. Take a negative wire from the horn harness and attach it to the remaining terminal on each of the horns.
Attach the grounding bolt to the car frame. Word of advice, do not use the horn bracket as a grounding point because the part of the vehicle that it attaches to is plastic.
Attach the relay somewhere so that it doesn't flop around. Run the long wire through the engine bay to the positive battery terminal. Be sure to zip tie the harness along the way.
Remove the fuse from the fuse holder on the horn harness.
Attach the horn harness to the positive battery terminal. Connect the battery
Place the fuse back into the fuse holder
Test your horn to make sure it works. Honk it 10 - 20 times. Vary the amount of time you hold down the horn. Congratulations, you have a working horn.
