On the switch, you mean the lock cyclinder or the electrical portion of the ignition switch ?

Do you have power on the yellow wire off of the ignition switch when the key is in the start position ?
Is there power to the yellow wire a the clutch switch ?
If you have power on the yellow wire with the clutch switch jumpered, (Not a safe idea), do you have power comming out the other side, Purple wire, ?
