Can someone tell me what exactly the "valve glow stater switch" and the "cam glow starter switch" are?  Is this a funky technical name for the ignition switch (key)? Will I need this to make this citcuit function properly when the engine is installed in my Jeep?
TIA,

It's the vacuum portion of the Ignition Key switch assembly. When the switch is in the run or start position, the cam causes the vacuum to be disconnect from the shut off circuit of the Injection Pump. When the key is switched to off, the cam lets the valve open and connect the vacuum supply to the shut off circuit.
