New wire harness, which one to use?

Just finished with Painless; will never use them again. The kit I used (10307)is oriented for GM. My car didn't have any wiring at all so I had no reference points. No schematic as to wire origins or explanations. However in their defense the kit I used was bare bones. Someone sells a kit specifically for Mopars not sure who. Keep in mind though it was my first attempt as I'm a butcher not an electronical engineer. Good luck
