TE/TC Installing horn to my te300

Any advice? I bought a warerproof horn and kill switch, should i tie into battery directly with inline fuse or some other simpler method? Thanks guys for your experience

Could tap off starter switch unless its lower voltage, need 12v. Havent snooped around yet

I recently converted mine to street legal.Originally i wired the horn off the generator with original the factory power and ground supplied for the lighting.The sound output from the horn was weak.Ended up running a fused lead from battery to horn and ran a new ground from under the tank where the other grounds are located near the coil and all was well.

Doesn't your American models come out with the wiring for a horn or have one installed?

Doesn't have one installed... There might be factory wiring already there for it though as my te300 has a couple of plugs underneath the headlight mask that aren't plugged into anything... I assume for blinkers. Not too sure if there are more underneath the tank or not. Seems to me there would be

I'd be surprise if Husky/KTM supplies the TE in Aust/Europe and USA with a wiring block that is fairly std...it's easy enough to wire one was it need's a power source and one to a button, they are usually grounded via the bolt.

Im sure its easy, just want to do the easiest route, i havent inspected it yet. There are extra wires but its off the computer, i called dealer on these and they dont know what its for. I figured it was for RPM or temp guage?

This off the 2013 KTM 350 Manual (USA), and l don't think the wiring diagram has since changed:

Whats off there (manual) your paragragh earlier is confusing to me, sorry

Ok, i see now. No pic when i clicked first time

You may have better luck researching a 300 exc manual for eu or Australia to get a better baseline. I'd think the 2 stroke and 4 stroke don't share the same stator design.

My manual should list this. I bought the CD manual because i couldnt find paper version for my 16 or a 15. Now im stuck trying to find a way to download it to a pdf to get it copied and binded to a paper version, i like a manual in my hands

The horns can come in 2 versions 1 being an ac voltage horn the other being a DC voltage . This makes all the difference in the world when you go to hook them up . My 98 Te610 worked off an AC voltage horn, this came with the EURO wiring harness that came on the bike . To use a DC voltage horn would have required a rectifier and not just the voltage regulator that came with that bike .

On the husqvarna website all manuals are available for download. I would check out the eu or au manual to see if those bikes are factory equipped which my guess would be that they are but who knows

This kit comes with some necessary items for street legal conversion. It has horn and the description states that it all plugs into factory harness. I paged through the eu manual and it shows they have all road crap on them over there including horn which between the two definately means that this should be true plug and play once you find the right plug. I would possibly consider trying to find all the oem stuff but that's just me.... Might find it off a street legal 4 stroke??? At least the switch and some of that part of the harness might be the same...seems to me it would be....Maybe... Just food for thought

After some research the unused plugs behind the headlight mask are for the oem blinker/horn/hi-lo switch that is indeed the same as the 350s and the 501s. Rocky Mountain has them and there appears to be an additional harness as well for the rest of the crap that most likely goes under the seat. Looked under the oem parts finder. I like how they have the schematics! Pictures always help. Will verify once I'm home from work that the plugs on the oem switch are indeed the same as my te300 but my opinion is if the wire is already there use it instead of running more.

A 6v AC horn will work on a 12v DC system no problems (just louder) as l've transferred by 2T horn to a roadbike with no issues. The DC horn doesn't need a rectifier just a voltage regulator as it doesn't care whether the voltage is AC or DC, just requires a 6-12v source. Your typical reg dampens the voltage to an acceptable 12.5-14.4v which is the reason 35/35w and tail lights all work on previous enduro 2T's with correct lighting coils whereas MX bikes typical don't have lighting coils.
Anyway, your modern TE300 will have a regulator/rectifier and the KTM/Husaberg/Husqvarna wiring system (at least where the handlebar switch is concerned) is universal for these models...just following the wiring diagram and find the right connector for the plug and away you go.

Screw it man, just do one of these...

You know this is still road legal as a horn in Aust...totally useless fact but true

That baby's got sum style OMG!
