I want to redo my wiring harness (engine) because it is the original wiring that was tied in for electronic ignition.. Here is what i'm working with. a lot of the wiring is cracked

70 Challenger, 360 engine, automatic, electronic ignition
do in need to put in the ballast resistor? currently it is a dual post.
could someone post a schematic or tell me where to look. If i ordered a new on should it be for a 72 Challenger because of the electronic ignition. is there anything on this forum

Thanks
