As long as you wired it to the stop light wire you should be fine, I and others have wired leds to the stop light wire and not had any problems. This is a straight 12v off the brake light switches. The issues are not the same as the wing since we dont have much or any can bus circuit. The real problem with our bikes is the use of leds and the modules to power them. But each module acts pretty much independent of the other.
Can bus is more like a communication line between modules so each can communicate with the other. If you want to start your car the ignition switch communes with the power module and then talks to the engine control module, dash module, ac, light, wiper and other assorted modules to turn on.
As an example,
If you switch on your lights the light switch is manually turned on, that sends a signal or code to the front sam (signal acquisition module) that goes to the headlight module then if you have hid goes to the hid module and your headlights turn on. But in doing this the front sam can send a signal to the engine ECU to raise the idle up and in turn raise the alternator output and also may send a signal from the light switch that may turn on the instrument cluster or it may have a light module that turns on the various other lights around the car. All this communication is the can bus responsibility to act like a phone service between all the modules.
The wiring for a can bus line is usually whats called "twisted pairs" wires of small gauge twisted tightly together to stop electro magnetic interference in the line. Old phone lines were twisted pairs, cat cables like cat 5 and cat 6 are twisted pairs.
All of this requires programing, communication, and each module has to be introduced to the other so each knows its ok to speak to that module and a whole host of other issues. Not to mention there is NO standard in how signals are routed so each manufacture, even each car has different routes and different modules to do the same end result.
In the can bus signal being digital it can have a far greater range in what it can command an electronic module to do. Simple signals like on off of a 12v circuit are easy, like our stop lights, but telling the dash lights to come on at 1/4 brightness can be communicated over a can bus line, module to module or to dim or brighten lights in response to ambient lighting.
Voltage on a can bus line is not enough to power anything and its not constant. If you short a can bus line you take a chance of blowing out the module that supplies the power to the can bus line or something else in the line.
If one module ties up the can bus line it can cause all sorts of seemingly unrelated problems. The only effective way to diagnose a problem like this is to disconnect modules till the modules start come back and communicate with each other and the function that they control works again or check the voltage of the can bus line. Some will say check the signal, which is possible but requires knowing the signal.
I doubt if the 2014 wing uses can bus, the new wing I believe does. If this seems a bit long its not. Can bus lines are a pain to deal with when they go out and they are simply complex. So if that statement confuses then you are at a good place to start to understand can bus.
