Hello all. Looking for some help in the electrical department for my FXDLS. I recently acquired a moons mc fly eye headlight for my bike (2016 FXDLS). I thought now was a perfect time to also install one of the LED light bars as well. I'll try and make this short and sweet, and yes I have read other threads regarding this, but haven't really found the answer I am looking for and not really sure about this entire can bus system and really trying to get clarification on it. I was thinking of wiring it a couple ways

1. Tie into low beam, that way it is always on with the lights no matter what.My concern is, if I tap into the low beam, do I run a risk of overloading the system? I know I'm only talking about another roughly 2.3 amps (1.5 amps from the bar and .8 amps more from the moons mc fly eye. Stock bulb I believe is max 60watts and the fly eye is 70, so total of .8 more with the fly eye) but I'm not quite sure how the amperage works considering there are only three fuses and not sure which fuse even goes to this circuit.

2. The above but tie a switch on it to control whether I want it on or not. (Can I do this? Is there any additional need for relays, or resistors?)

3. Run a fused cable to battery with switch. (Not sure I like this idea, as then I have the possibility of accidently leaving it on. But might be the easiest way to go about it.( This with this)

 

Here are the wiring diagrams for your bike

Thanks for that. In doing some more research, I came across that Harley has an electrical connection upgrade kit. I like that idea as it is then connected to ignition on and no power if the bike is off. My question now is that I ordered this (Wiring Kit) already, can I just buy the Harley connection kit and just plug the positive and ground wires from the kit into the corresponding spots on the Harley kit and still be able to use the kit? Or can I not do that considering the kit comes with a relay and fuse already wired into?
Sorry the more I research, the more I confuse myself. I'm thinking is should be able
