I found a wiring diagram for 1972 here - http://midlife66.com/wiring/wiring.html
it shows that the wire comes from the distributor to the negative side of the coil. Then, from the positive side to a breaker? What is this breaker and where is it located?

I see no breaker.....just a couple of plugs as it goes thru the fire wall and under the dash. Looks just like all the other stock wiring systems for Mustangs. Do you have the factory gauge harness.....the one that has three wires in it...one coil, one temp sender, one oil sender? That has a wire that gor=es to a pink wire under the dash.....and it is a resistor (pink) wire for a lower voltage to the coil.
Could the breaker be the points? Usually, the coil from the underdash goes to the + side, and the - side goes to the distributor and points. I've seen where the points are called the breaker.
Those wiring diagrams are really poor. What is called the "breaker" is the connector for the oil, temp, and coil lines, typically just forward of the firewall.

You need one of these: http://www.parts-express.com/pe/showdetl.cfm?Partnumber=390-500 and start doing some diagnostics. Heck, as crappy as the schematics can be for these cars, you probably need one anyway.

Midlife, would it be too much to ask you to draw up a little better diagram to work with without all the lines? Or are you able to?
Those diagrams were taken from another site back in 2000, and they are simply scanned versions from Chilton. The actual Ford diagrams are 11x17" and there are 7 of them for 1973. I have no desire to re-draw them...

It is very simple to follow the wiring diagrams if you study them a bit. Try printing them out and then you can hilite the ones you need as you follow them.
