I was looking at the diagrams in the sticky up above, and I have a question about http://home.comcast.net/~phantoms/vacuum/IP_shutoff.jpg

Can someone tell me what exactly the "valve glow starter switch" and the "cam glow starter switch" are? Is this some kinda funky technical jargon for the ignition switch (key)? Will I need the key switch from the donor car to make this circuit function properly when the engine is installed in my Jeep?

TIA,
Don
