Very easy solution. Just procure a connector set (I use XT-90's with spark arrest; got mine with "pigtails" from Luna Cycle, but they're everywhere) and solder or use crimp connectors to join. If you get them with "pigtails" you don't need to worry about the plugs, just connect the wires. Experts like DY probably don't need to do this.
Took a second look and if you can find the appropriate "bullets", you only need to put them on the bare set; however, I'd get a more durable system.
