Brute Won't start

I have 2011 650i that won't start. I recently had some of the electrical components pushed aside to replace the fuel filter which I didn't change because I found out my bike doesn't have one because it's the carburated version. After reassemble my bike now won't start turns over great but not getting any power or fire on the plugs. I am thinking I possibly broke a wire. Where can I find a wiring diagram for this bike ? Where does the supply from spark plugs come from the CDI ? If so which Plug? and I'm open to any suggestions for troubleshooting.
