e-z wiring harness start

[charlie challenger]

I have a '70 challenger, and bought an e-z wiring harness to rewire it.  The diagram that came with the harness isn't very helpful, but all the wires on it are labeled every 6 inches or so.
I put a rebuilt '76 440 in it, electronic ignition, and a 100 amp alt.  so there are a lot of variables to consider.  I thought I'd start here to ask if anyone has any advice, or things I should look out for. 
I pulled an electronic control unit from a van at the junk yard, allong with a 4 prong ballast resistor (don't need the 2 prong right?) 
Also, there are 2 wires to the alternator, one labeled alt power, the other alt excitor.  My alt has power and 2 fields.  I saw a diagram that showed the alt. excitor splced after it came from the bulk head, one connecting directly to one field, the other passing through the ballast resistor and connecting to the other field.  Does that sound right?

This diagram is right... right?

if you wire as the diagram you osted you do not use the green wire from the ECU & you use just a 2 prong ballast , the blure wire & the ballst both connect to the 12 v switched wire from the ign switch
 the wiring you have is GM based , you also need to connect 12 v switched power to a voltage regulator & & directly to on of the field terminals on the Alternator , the other field wire is the green wire from the voltage regulator . when using a 100 amp alt I suggest you also run a 10 ga wire from the alt output directly to the large stud on the starter realy , the factory ammmeter guage & the bulhead connector are not designed to take 100 amp load
