step 14 to 18) The Hella horns can be mounted at existing bolt locations on bumper impact bar, two above and two below. due to space limitations the sharp tones - yellow horns need to go above next to head lamps and super tones - red horns need to be below. Normally I would prefer to mount horns so they could be seen when looking through grill, however it would be a BAD idea to mount in front of turbo intercooler also radiator support air dam is made of plastic ( would have been too involved designing suitable bracket to mount horns, also best not to restrict air flow to radiator ). In the end when bumper cover is reinstalled you can not see the red horns, you can get a glimpse of yellow horns thru upper grill if viewing from angle. Not to worry though, you will absolutely have no problem hearing these as all four are facing forward, use with discretion but without reservation when needed!!
step 14) arrow showing lower bolt location on passenger side impact bar, remove bolt and discard
step 15) horn is mounted using a longer 8x1.25 flanged head bolt, 8mm external star washer on each side of Hella horn bracket, and a spacer so horn bracket is not distorted by raised edge of impact bar bracket ( see arrow in picture 15 ) Hella horn bracket needs to be set a 45 degree angle towards outside of car to allow for clearance of fog lamps if equipped
step 16) arrow showing upper bolt location on drivers side of impact bar, remove bolt and discard, utilize same longer bolt & star washers & spacer, Hella horn bracket needs to be set at 45 degree angle towards center of car for clearance between head lamps and radiator support
step 17) showing horns installed on drivers side, arrow showing wiring for both left and right pairs of horns and stock horn positive wire that was previously extended running up and thru opening under drivers side DRL and into engine compartment
step 18) all four horns installed, at this point front bumper cover can be reinstalled in reverse order of removal, rest of wiring will be done inside engine bay
