I have a 2016 Breakout and can't figure out which wire to hook up to the sound bar so that it doesn't drain my battery. The instructions that came with it are very vague but they say to hook it to the ignition wire but I don't know which wire that is and don't want to cut any wires that I don't need to. Thanks for your help.

 

I have a 16 Heritage, and I was able to buy an adapter that gave me a switched wire out. I suspect that you may need three wires: Switched (sometimes yellow), postitive and negative. I'm assuming when the unit receives switched power it will then begin to draw full current from the positive lead.

Something like this:

or this: https://www.harley-davidson.com/stor...dapter-harness (You'd have to cut off one of those ends. But it leaves the plug available for true connections.)


I went a completely different way with my setup. My post might give you some ideas.

In my case, I did a physical switch on the handlebars instead of using switched power. This way, should I want to listen to my music while I'm not riding the bike (or leave my LED's on at a bike night, rally) I have that option. Note: I am a computer programmer, so that gives me a bit of an edge on wiring up a bunch of stuff! Also, I tend to over-engineer.

 

Let me also add that when I added LED strips to the wife's Sportster, I didn't use an adapter. I have a cheap Harbor Freight multimeter and I poked into the wires between various connections until I found the switched power line. Runs at low voltage, like maybe five volts, I then tapped into that line and ran it to a relay. (The LED controller in this case didn't have switched power support of it's own, plus I was wiring in a USB charger for her phone, too.)

The multimeter is really important, IMO, for doing any electrical work on the bike.

In this case, I keyed on the bike, started poking the positive lead into wires through the insulation (don't tear it up, it's there for a reason). When I found one, I'd turn off the bike, check again. If it's dead now, it's probably switched. That doesn't mean it's the true switched power circuit intended for that, but a relay uses a trickle of power to allow the main power circuit to complete. (Pretty neat, I didn't understand them until I read up when the wife said "I don't want a bunch of switched I have to fool with. I just want to turn on the bike and go and everything has power." I was lucky that the LED controller turned on the lights w/o a separate remote button click.)
