I don't know what it's from, but i'm going to run it on my cb500.

There is a solid blue and a solid yellow wire and a post for the ground.   Which is which on the blue and yellow?

Connect the ground post to the neg of your battery and tap the yellow and blue one at a time to the pos wire of your battery the brighter the bulb then its your brake the other is your running light. If I was to guess the yellow is your brake, and blue is running (I'm guessing).

Trial and error dude, you've only got 2 wires and a ground, nothing should blow a fuse or damage anything...unless the rest of your wiring isn't quite right...

Yeah I was just kind of afraid of blowing something up.  Guess it was kind of irrational.

Anyways, here is my set up I came up with.  The license plate is temporary.

I love the fenderless look, I'm thinking of losing mine but keeping the grab bar, I wonder how that looks?

You could trim the fender down enough so that it stops just below the grab bar, and then you could mount a new mini tail light on the end of the fender and it could look like it's just the end of the seat and a grab bar with the tail light mounted in the seat.
