On my 2A with 12v conversion, I did exactly what Gun suggested.  Bought a coil from NAPA, part no. IC14.  Has the internal resistor. $26.00 and change.  Came with a new bracket and other hardware.  Works great.

It looks to me like there is a couple things going on here, the battery  is 12v so this is a conversion wiring diagram, distributor is 6volts, coil 12 volts in the diagram.  A 12 volt coil actually runs on 8 volts, so you do have to drop your battery voltage down or it will overheat the coil and burn it out. Like mine did.  I would go to NAPA and ask for a 12 volt coil with a built in resistor, this will eliminate the resistor in your diagram and make your coil and distributor safe at the higher voltage.  

Your other option is to go with a 6 volt battery, then you can drop the resistor from the wiring completely, you will have to make sure you have a 6 volt coil if you do that.
Good luck and keep jeepin

Thanks John, I would love to take credit for it but I dug it up on the 2A page somewhere. Between the two pages you can find anything if you dig deep enough. I might add the Vernco site, great piece on polorizing the system.

Nice wiring diagram. Did you do it or did it come with a wiring harness?
I'm thinking you did it.
If so, nice job.

Thanks Bill/Bob W, my coil does not require a resistor. Bill no fusable link in the wire as I am wiring a temporary dash for a engine test (and hopfully a short run) on the chassis.

If your coil requires a ballast resistor just type "chrysler ballast resistor" into your favorite search engine and you will have plenty of info.

Check your coil, see if it is marked "for use with resistor" or "no resistor required".....

ALso take a close look at the wire in question and make sure somen hasn't wired in a fusible link or resistor wire.. Fusible links are normallyh marked as such, and the wire in a resistor wire is usually silver colored.

Between the coil and ignition switch in my wire diagram is a resistor. Do not remember seeing on on the tear down. Can anyone help me with size and type? � � � � � �
