High Beam wiring

[WyldCFH]

I installed a Screaming Banshee Shockwave horn today that can flash the brights when you hit the horn. Nice added bonus.

Anyone know which wire controls the high beam activation? The horn has 1 wire for this purpose, but I'd like it to trigger both headlights. Is there a spot coming out of the switch down to the lights that is is 1 wire to tap into?

I'll be using a post-tap, not cutting and splicing.

If not, I may pick up 6 or 8 led aux light and use it instead.

Blue/White wire
To either of the headlights or at the Left Bar-Switch connector or at the Instrument Connector
Regardless of where you select/connect it, BOTH lights will be operated (even if connected to just ONE of the headlights)

Note that when you use this connection, the Low Beams will NOT turn off, which means you will be lighting BOTH filaments in each bulb.

Also note that extra load from the lights plus the horn is going to pull about 28A!!!!
Make sure you're using Robust Wiring gauge (if your wiring gauge is too small it will actually somewhat mute the horn from its max performance)

The horn itself is powered by wiring direct to the battery, it just uses the stock wiring for button activation.

• • Will the Shockwave Horn system have any effect on my electrical system?
    
    No
    We have installed our systems on all kinds of motorcycles, scooters, and cars, including sports cars and smart cars. We have never had a report of damage to any vehicle wiring system. Our air horn does draw 25 amps (in short bursts),but that power is taken directly from the battery, completely bypassing the vehicles electrical system.
    

For the lights, I ave Chinese LEDs plus LEDs in the turns, brake and license plate. Hopefully it won't hurt much. They supplied all the needed wiring.

I already understand how it's wired - just saying you will see that draw from battery
With the LED lights - at say 3.5A ea - that will make 32A by that quoted 25 for the horn.

Oh ok, I didn't understand you. I have less than little knowledge of electrical wiring and currents. If I recall right from stripping the wires, their harness uses either 16 or 14 gauge wire.

Thanks for the info.
