7. From here, its time to figure how to reattach the horns. Things to keep in mind. They have to be close enough to still reach the connectors on the front of the car. They also have to fit somewhere stable (bolt to the bumper is ideal). Lastly, when you reinstall the bumper, they cannot get in the way of anything else on the car, so you have to make sure that won't happen. If necessary, test fit your bumper to make sure it'll still slide fully into place with the relocated horns. I chose to use one of the holes on the outer edge of the crash bumper. I had to bend the bracket a little to make it fit, but the connector is still plenty close to where it was, they're out of the way, and the connection is nice and solid. Pics below show this.
8. Once the horn is moved, now there is plenty of space for the placement of the HID ballast units. Granted, this worked well for me because the ballast units fit perfectly inside the crash bumper. If yours don't fit, you'll have to adapt this DIY. But I digress, I placed mine here. Its very important to clean all dirt from the crash bumper to ensure good attachment. I used Brakleen as it easily removed all dirt and also any oil resides, allowing for good adherence of the double sided adhesive pad. Differing units will attach in different ways. I used the kit supplied double sided adhesive pad and a couple of zip ties in addition to ensure a solid mounting. MORE than secure for a long time. Pic below...
