Hi,
I've searched and just can't find the particular answer. I am adding LED auxiliary lights to my 2016. I have the Eastern Beaver plug for the 3 wire connection. I understand Black is G, Red and White is 12v always on and Brown is 12v with ignition. My question is my lights just have power and ground wires. Is it okay to hook up to ground and 12v with ignition? And just dead end the 12v always on?
If not, I am stumped.....Any help would be appreciated. While searched through the posts I thought I read not to do that.....again, I am stumped....
Thank you.

No. The brown wire is a low draw 12V signal from the ECU. You don't want to put a load on it. It's to be used as Johnwesley said, to trigger a relay. Any standard 30 amp, 4 pin automotive relay will work fine.

Ground the lights to the frame off a convenient bolt near the light mounting. The horn mounting bolt works well.

The 12V power wire from the lights goes to relay pin 87.

The black wire from the bike harness can go to relay pin 86.

The brown wire from the bike harness can go to relay pin 85.

A 12V fused power wire direct from the battery goes to relay pin 30.

Wiring this way will result in your LED lights being on any time the bike is on. Some prefer to use the pink wire from the headlight harness for relay pin 85 so that the aux lights are on with high beams and off with low beams if the aux lights are to see with, rather than conspicuity lights for others to see you.

If you want a switch in the system, put a simple on/off switch inline with the wire going to relay pin 85. If that switch is illuminated, it will need a separate chassis ground.

Hope that helps.

That would indicate my memory is faulty and the brown wire would support LED lights. Nice share Boris. :)

Thanks guys. So I gather it is okay to use the brown wire???
I would say so with a fuse, if not if you do blow a fuse it's the ING fuse so you'll lose your ing system. This also depends on the amperage the lights use. Im not sure how much extra power is available on the brown wire with the IGN using some of that.
