This is my first DIY guide so if I missed something or confused you let me know and I'll try to help you out as much as possible.

This is the basic install for the Supertones Hella Horns. I don't have step by step pictures of the install but this should be sufficient enough to figure out how to install it. Difficulty of install would be a 3 out of 5. Most people should be able to do this easily. Here we go.

Thing you need:
Tools:
Wire stripper
Heat gun
Heat shrink tube
Wire crimper
Wrench or Ratchet with sockets.
Drill (optional)

Parts:
(2) Hella horns (comes two in a box)
(1) Hella horns relay (comes in the box)
(1) Spool of wire (14 gauge is good)
(8) Female terminals
(1) Male thin terminal
(4) Ring terminals (2 to ground the horns, 1 to ground the relay, 1 for (+)Battery)
(1) Wired Fuse
Some zip ties to keep things neat
Small wire loom to keep wires neat.

These are the basic things you need for the install IF you decide to use the holes for the stock horns.

If you aren't, you'll need to make a custom bracket. I went to home depot and picked up two metal brackets with pre-made holes from the plumbing section. Also picked up 6 bolts, 6 nuts, and lock washers.

Remember to disconnect the battery before starting any work.

First thing you want to do is take off the grill. There should be a guide on how to do it somewhere on here.

After you remove the grill, you want to remove the stock horns. Just unbolt them and disconnect the wires.
--------------------------------------------------------
This next part is only if you do not want to use the location of the stock horns.
If you are going with the bracket route, you now want to measure out how you want the horns to fit. Hold the bracket against the metal frame with a horn on each side. Try to match the bolt holes to the center of the metal frame. This is where you'll drill your holes. Now when your drilling, MAKE SURE you have a block of wood or something behind the frame. I didn't and accidently when through and hit the AC condenser like an idiot.
-----------------------------------------------------------
Now you must make the wires. Follow this guide and it should be very simple.



85 - Ground
30 - Fuse>(+)Battery
86 - Stock horn connector
87 - Hella Horn (+)

Make all the wires into whatever length you want to run them. The two (+) wires for the horns should be wired together and then to pin 87.
I wired the grounds for the horns onto the metal bracket that it came with.



Since I made my own bracket, I mounted the relay where the stock horns were. For the connection to the stock horn connector(pin 86), I just stuck the male terminal into each hole to see which one works. Don't worry about the other horn connector, you only need one to set off both horns.

Once all is wired up, reconnect the battery and test out the horn, if they work SUCCESS. If they don't go over your wiring again. Mount the bracket using the holes you drilled and make sure both horns sit about even. Put your grill back on an enjoy. :D

Here is now it looks with the oem grill.

LMAO! I can picture drivers stopping dead in their tracks (no pun intended) when they hear that thing. I gotta get one.

Just bolt them up to the stock location and mount your ground wires where the oem bolts go. I just made a bracket for it so it would be even, instead of one higher than the other.

Has anyone found anything a little more agressive that those Hella 'super squeek'?

One of my OEM horns went out and I honestly would prefer leaving it as it is than spending that kind of $$ on those Hellas.

I have an dual trompet air horn on my jeep that, if I could, I would pon on my GC.

Where is a good place online to order these?

Ok so bought the horns on amazon. Where is a good place to buy all the wiring hardware (fuse, terminals, wire, etc) for this project?
 
#24 ·
I just put these in any my car sounds like a 1980 VW Beetle. I don't think the higher-pitched horn is working. What is going on?!?!? Ahhhhhh

bumping an old thread. The stock horn on the genesis sucks. I had the following horns on my 05 accord and will be getting them again for the GC:


The OP shows a relay and a fuse, i think the horn kit comes with a relay, but what about the fuse? Also, What does the stock horn connector connect to the hella relay?
 
#27 ·
fuse is optional

Stock horn connector has both a positive and a negative. Depending on how you wire the horn (for positive or for negative), you'll need to stick the male terminal into 1 or the other contact (on the same connector). There are 2 connectors for the stock horns (1 each) and you only use one so you just tape off the other.

So i installed these over the weekend and couldn't get them to work. I had them hooked up just like in this thread but i didn't use the fuse. I even tried hooking the horns directly up to the stock horn power cords and that still didn't work. When i installed them on my 05 STI a few yrs ago i wasn't able to get them to work with the rely as well so i just ground the hellas and used the stock wires and they worked fine but thats not the case this time. Anyone have any ideas?
