Welp unfortunately there isnt anything unless your wanting to replace the entire wiring harness through out the car and at that point id get a painless wiring harness. But about two months ago i had a starting and charging issue, found out it was one of the wires that went to the starter that also connected the battery and rest of the entire cars power supply. So i went and bought about 10 feet of 8 gauge and 10 feet of 10 gauge. So i replacedmost of the wiring in between the battery, to the starter, to the alternator, and all the way to the fuse box were i spliced it in, Also changed the battery cables since i was there. I had also upgraded to a 108 amp alternator and i think the factory size was a 10 gauge, didnt have any issues with it but for safety i replaced it with 8 gauge. Since i upgraded the alternator and was upgrading the wiring, i also added a 150 amp mega fuse inline from the battery to the rest of the car. Then i wrapped some of the wiring in heat shield since those starter wires are so close to the headers. The wiring harness is pretty simple well i mean it was for me, just replaced one wire at a time. And now no more issues with starting and charging!
