Help Lifan owners, where does it hook up???

[Ridgeline]

Hi Guys, I finally got my GY-5, I am almost finish the assembly but I have a wiring problem?!?! Where in the hell does the shifter diode hookup go, I think that's what it's called?? It has a 2 wire plug with a wide flat black hookup on the other end and it looks like it fits with a screw or something and it's about 8 inches long.I got no instructions with the bike and am putting it together on my own, I could not find an assembly page download and am winging it!! I hope the Chinariders can help. Also does your bike have 2 unused plugs in the wire bundle, like mine??Thanks Guys...
