Hello everyone! I just bought a 2002 ls650 and I noticed my horn doesn't work. So I took it apart and tried to follow the circuit but I can't find my horn?   haha I'm thinking the guy I bought it from tried to upgrade it, took the old one off and just never finished...
Odd request... but do you guys have pictures of your horns location? Even better can someone walk me through how to put a new one on.
This is indeed an interesting situation, and I appreciate all the help! haha

excellent. In that case I have no horn. But I surprisingly have no lose wires. Maybe I'm not following the circuit correctly, but i'd expect very apparently unwired inputs. but nothing. okay... back to the drawing board xD

There's diagrams in the tech section.

Perfect opportunity to get a car horn from the junk yard,, and grab the relay, too,, Get one that Needs a relay,, if it doesnt, in my experience,, its not loud enough.. I can literally holler loud enough to get someones attention when the stock horn has failed,,
Find the wires from the button and wire it up.. May hafta pull the tank.
Another fine opportunity
You can change the seat bolts, make them longer and set jam nuts on them,,You can shim the seat front up.
And you can check and add grease to all the connections under there..
Cant remember the name of the stuff,, Okay,, looked on the lube shelf,, Dialectric connection grease,, you can get a little packet at the parrts house for a buck,, I Think the button supplies the ground, and one side of the horn is always hot,

Great suggestion Versey, have not looked at those for a long while.  Its a wealth if really nice photos of virtually everything on the bike.

That was certainly an invaluable resource!
However none really gave me a good view of the wiring leading up to the horn, and being such a novice when it comes to bike, I was wondering if any of you have any close ups of the horn on your 2002 ls650.

It really doesn't even seem like I have one. I was really getting in there, and without taking the tank off, I really don't know how else to go about this.

This picture shows a close up with the horn removed.  You can see that there is a black/red wire and a black/blue wire.  That agrees with wiring diagrams from 1996 to present.  Earlier models had black/brown & green wires.

Thank you all for all your help!
DragBikeMike, you are a saint!
Your pictures are very helpful, and I can confirm I certainly have no horn xD
Now I just need to locate those wires and just hook one up...
But as far as I can tell there are no loose cables...
I'll send pictures as soon as I can!
