Other Need Electrical Help

Hi. I have a CRF125 and the ignition switch went bad and then the wiring harness damaged. The wires to the engine stop button, ignition switch are bad. I plan to get it all replaced, but in the meantime I'd like to ride it with a manual start. I'd like to bypass the ignition switch, engine stop button, starter button, etc. I think I need to satisfy all the inputs to the Ignition control module and then I can start the bike. I've attached a drawing I found on it. I tried applying 12V to the Bl/W line to the ICM thinking that would allow the bike to just start, but it doesn't work. Everything to the starter relay switch, rectifier, alternator is still intact.\

I know it's tough to troubleshoot without seeing it,but if anybody has any ideas let me know.

If this is the correct wiring diagram, then this should be real easy to fix.
-Kill switch can be disconnected, and the bike will run, but will need to be stalled to kill it.
Grounding the Black/White wire from the CDI will KILL the ignition. Clip and terminate to be sure it's not grounding out.

-Black and Red wires in the ignition switch need to be connected to give the starter switch power.
-The Black/White and the Green wire should not be touching in the ignition switch. You can clip and terminate to be sure.
