Been asked a few time how I wired the halos for my projector headlights, well I took a few pictures so that you can see. I just took the red positive and black negative for the halos and spliced it into the positive and negative wires for the marker lights.







Hope that helps, you can splice the wires in however you see fit as long as the metal is touching and there isn't any exposed to any outside elements. I'll redo mine with a more professional splice job when I get the chance.
