I didn't take a picture. It is just a little 3/4" square box about 1/8" thick with 5 wires coming out of it. The black wire hooks up to a ground. The Yellow wire goes to the wire from the brake. The Red wire goes to the brake light. The white and blue wires are to set the flashing brightness, how many flashes, etc. I put is under my seat and I tie wrapped it to the bar that goes across the bike.
