Trying to wire trailer lights

Which wire in the tail light assembly provides the brake light signal? I have left turn, right turn, and running lights all working but have been unable to get brake lights. I am tapping the wire just before the lights right in the fixture.

Re: Trying to wire trailer lights

Brake light is the Gray/Yellow wire and Brown is your ground return. Do not use the frame as you would in a car.. I highly recommend you use these lines you have to drive relays as the main harness wiring will not handle the load of trailer lights unless they are all LED.

I tapped into the wiring under the pax seat and wired in relays for all trailer lights. Protects the bike's circuits as John said. Tapping in this location was easier and cleaner than running the wires from behind the tail lamp assembly.

Thanks.

I tagged a fresh lead off the wire and now everything works!
