Well kids, here we are again. Its spring, and there's something in the air that gets me all excited to do some mods.
I bought this thing a while ago,but I glanced around the engine compartment and couldn't find a mounting location for it that I was 100% happy with...especially since I actually READ the instructions and they state that the horn should be mounted with the trumpets facing DOWN....otherwise water can't drain out of them.
I've seen someone mount them sideways in the bumper, so that the license plate covers most of the compressor and the horns stick out, but I wasn't happy with that either since all kinds of road junk and bugs would just get lodged in there...so I put it away for a while.
This morning, I woke up, and not only did I have morning wood, but I also had a great idea where to put horn....so here's the write-up.
First of all, if you want this horn, its from Griot's garage. It sounds just like a Ferarri horn, and is really really really really loud...139dB is a bit louder than a jet airplane I believe. People WILL hear you even if they're in one of those huge SUVs with 20" subwoofers blasting. Its $39....totally worth it.
before you start you should make a ground wire for your horn. All you need is a piece of decent-gauge wire, a crimp-on battery terminal and a crimp-on female spade connector. I soldered mine for extra style points, but I'm sure crimping works just fine. It will look something like this:
next, we attack the car! so where is this brilliant location? right behind the driver's fog light! I know I know...you guys with FMIC's are probably saying "oh great, that doesn't really help me", but you're wrong! you can also mount this (although with a bit more difficulty) on the driver's side fender...in the same place the silencer is on the other side.
so...here's the procedure:
1) disconnect and remove the stock horns. The one on the center support comes off pretty easy, but the bracket near the headlight was a bit more of a pain....rather than removing the headlight and all kinds of trim to get to it, I just unscrewed the horn from the bracket, and left the bracket..its not really in the way. The big bolt is 12mm and little bolt on the back of the horn is 10mm
2) tuck the wire from the center horn under the bumper trim so its out of the way and not flapping around.
3) get under the car. Remove the plastic clips holding the brake duct, and take it off.
4) remove the 2 big clips that hold down the lower apron and pull the plasic back to gain access to the area behind the fog light. In the second picture you can see the hole in the metal that we will use to hang the horn on.
5) the hole is not quite big enough for the bolt that came with the horn. Just drill it out to the right size.
6) get back up. follow the second horn wire to where it starts (large bundle of wires in front of the battery, and pull the wire so you have the entire length of it next to the battery. then feed the horn wire down into the space you just opened. (black wire in picture)
7) connect the negative spade connector on the horn to the gound wire you just made.
8) assemble the mounting hardware on the horn, the bolt head goes in the metal slot, then the plastic square...makre sure the tab on the plasic square fits into the slot on the horn...it keeps things from twisting. Then tighten ONE nun onto the bolt.
9) Put the horn in its plase, and before you put on the other nut, get the other end of the ground wire with the battery terminal connector on the bolt. tighten everything. Its a tight fit, but not terribly difficult. I was able to get in there with a 13mm wrench with a slightly bent head.
10) plug in the connector from the old horn that you just fed down here into the positive terimnal on the horn.
11) test it.
12) change your pants.
13) if everything works, grasp the horn firmly, and push up on it to bend the metal tab that it's bolted to just a bit. It doesn't take much, but it will move the horn out of the way so you can close up the plastic apron. don't go crazy here...measure so do you don't end up bending it any more out of shape than is necessary...it won't hurt anything if you do, but hey, neatness counts.
14) close apron and re-install brake ducts.
15) go for a drive, honk and people and watch them poop their pants.
