ignition coil questions

My ignition is wired up wrong from the idiot who owned the truck before i got it, the engine is a crate 360 magnum it was purchased by my old man bvrand new from the local dodge dealership in 2002 it only has 20 to 25 thousand miles on it, it's rated at 300hp and 375 ft lbs of torque but its probly pushing 320 hp and darn near 400 ft lbs of torque with the headers and dual exhaust with an h pipe and and a dual plane edelbrock rpm air gap intake and a manual choke edelbrock 600cfm carb.
I ordered a new electronic ignition wiring harness because the harnes thats on it is very old and hacked up, thats why i was asking questions on how to wire the ignition up, wich you helped me out with alot 67dart273, thank you by the way, i printed off what you told me and the pictures you showed me. I bought a new borg warner select ignition coil, a new borg warner select voltage regulator a new standard x-series ignition module and yesterday i purchased a brand new 2 prong ballast resistor from car quest. I wdecided to run the 2 pin ballast because it looked easier to wire up then the 4 prong ballast i have now, the standard ignition module i bought is a 4 pin module, i had that double checked by the way... so i figured since im going to be running a 4 pin module i might as well run the 2 prong resistor, make it as simple as i can because i am not the best there is at wiring, but i have been asking alot of questions and reading a bunch of stuff on the mopar electronic ignition. I'm going to pop the cap and rotor off and make sure they didnt get hurt, i think they should be ok, the cap and rotor i bought brand new in november and i got the echlin cap from napa and the echlin rotor from napa.
Just like you had said 67dart273 the ignition on my truck is wired up wrong, i followed the wire from the positive terminal of the coil to the ballast resistor and the guy that owned it before has the coil running on the wrong side of the ballast, thats why when i turn they key on and test the coil im getting 12.5 volts to the positive terminal of the coil, instead of messing with this hacked up harness and digging thru this guys mess i decided to order a new harness and get a new coil and voltage regulator and ignition module and 2 prong ballast, i tested the new ballast with my meter and it shows 1.2 ohms wich i have been told is correct? Anyways i was just mearly trying to learn a little bit more about the mopar electronic ignition by asking about the coil and ballast, im sure once my ignition is wired up correctly it will sound much better and run much better and hopefully i will get better fuel mileage then i am getting with it right now, i think that ignition being wired all wrong has something to do with my 10 miles to the gallon regardless of how hard or soft i am on it. thank you for all your guys help with this, if any of you have some more information or pictures to share with me regarding the mopar electronic ignition and how it works and how to wire it up please feel free to share with me, i knew a little about the mopar electronic ignition from a 76 half ton dodge truck i owned a few years back, but it was wired up correctly and i never had any problems from it.
