*Need help on how to wire up a switch panel*

I'm trying to wire up a switch panel in my Duster with a master switch and start switch (along with fuel pump, water pump, and fan switches), but I'm running into a problem. I've got them wired and the start switch works to turn over the motor, but I'm not getting anything to the ignition system to keep it running.

Here's how I have it wired (all wire colors are the ones to the stock ign switch):
Red in to Master switch, then out to start button
Yellow and brown to other side of start button
Black not hooked to anything

I had the blue one to the out side of the master switch because the way I read the schematics, it looks like it supplies power for ignition, not the starter, but when I had it hooked up, it would crank when I flipped on the master switch.

I've gone over the schematics several times, and can't figure out why having the blue one coming off the master switch makes it crank. According to the schematic, the blue wire eventually supplies power to the brown wire on the coil.

Where am I going wrong?

Thanks,
Dave
