Your solenoid is wired wrong. You can't have the battery and starter motor on the same pole. The left pole, currently going to ground, should have a connection to the starter motor. Omit the ground connection.

Are you planning on running the M-Button?

The open line at th "points/ignition" box, why do you have that? Are you running points or electronic ignition?

You should be running power to the ignition directly from the AUX port. Power to the coils you can run through the KILL switch, but those Emgo switches will probably not enjoy the amperageor long.

The RED lead you have looped from the LOCK port to M-Unit power is wrong. Battery to M-Unit. Key BLACK wire to LOCK.

Have a glimpse at this PDF to tide you over until I finish yours tonight.

Hey Cal,
- yes I'm running the M button
- I'll be running electronic ignition (Dyna DS1-2)
- So if I don't the kill switch through the coils 12V should I connect it in series after the ignition switch?
- I have the two colors before the lock to represent the key switch (I thought that's where you connect the key)

Thanks for the PDF and thanks for the help!
