Stebel Nautilus install on 02 S3

[02S3]

I just finished installing the Stebel Nautilus Compact. Here is a short synopsis of my install.

The package includes the horn unit and a 30 amp relay. I'm not great with electrical stuff but the wiring was not too difficult. After one mix up I had everything sorted.

I mounted the relay to one of the screws that holds the undertray to the subframe.


Wire splices were used to tap into the stock horn wires to trigger the new relay from the horn button. I disconnected the wires from the stock horn and pulled them back to the battery area. This is where I had originally screwed up. I thought that the S3 had a hot lead to the horn button. Apparently it has a ground lead.


The relay and horn is wired like this:
The 12v in terminal (marked 30) runs to the positive pole in the battery through a 20 amp fuse
The ground terminal (marked 85) is wire spliced into the purple/black wire that originally went to the factory horn
The trigger terminal (marked 86) is wire spliced into the orange green wire that originally went to the factory horn
The 12v out terminal (marked 87) is run to the positive side of the horn unit
The negative side of the horn unit is run directly to the motorcycles electrical ground.

My next goal was to figure out where to install the horn. I originally wanted to install in on the back of the battery box above the swingarm pivot. There wasn't enough room there so I decided to place it near the front sprocket cover.

I made up a bracket to attach to the top two screws of the sprocket cover. I used 1/16" steel cut on a band saw and then fished on a bench grinder.


I painted the bracket and installed it onto the horn unit. I used an M8x35 screw, nylock nut and 4 washers as spacers. It needed to be spaced so it wouldn't rest against the sprocket cover.




Here is the finished product. It fits into the small void pretty well.

*ETA* I removed the original sound file links. They got screwed up somehow.

Thanks for the post - I put a little aftermarket horn on that was louder, but not much. This looks like jus the ticket. You didn't happen to make a patter for the bracket did you?

Thanks

Excellent!

Thanks

ROFL!!! :roflmoa2:
I have a surround sound system on this computer and I just downloaded and listened to the sound file of the Nautilus. My dog just about jumped out of his hide, and he is still standing there panting as I type this!! I hope that horn has a similar effect on the mindless cagers on the street!

Good luck!

I already put a Stebel on my T100 and was just geting around to fitting another one to the S 3 (it is in the shop-dont run) so this should work out for the 06 model as well-darn close at least -thanks for the how-to write up and as you knnow they are super blasters!!!

Hey 02s3.

I just noticed you used those little blue "Fold-over" wire splices.

I highly recommend you remove them and replace them with good soldered connections.

In my opinion these "Fold-over" splices should be illegal. I can't tell you how many times as a professional mechanic I've spent hours tracing an electrical fault down to one of these things. If you look inside them, the way they work is to actually cut the wire in the process of splicing. This can, and often does, lead to intermittent contact. Particularly if they get wet.

Soldered connections are 100% secure. They take longer, but are really worth it. It's actually easy, so I recommend learning how. Use shrink tubing to cover the joints.

How to solder wires

If anybody is interested in a tutorial on soldering wire joints and connectors in motorcycle wiring, let me know. The above link is more applicable to electronics.

I got my soldering iron out and will mount a Stebel tomorrow PM on the S3. Old Whitey should be home tmorrow.

HiVel-

Did you get your Stebel mounted? I have an 06 S3, and was wondering how the install went on yours, and how different it was from the 02 install...
