I was reading thru the big 3 thread and I want to know why I have to use an additional wire for the negative battery terminal? My battery is in the trunk and it is far easier for me to remove the original negative wire and replace it with a 0 gauge wire. I don't understand why I need both. My car is no longer under warranty so removing and replacing it is not an issue for me. Any thoughts? Also has anyone here done the big 3 on either a dodge charger, magnum or Chrysler 300? I need tips or tricks since the battery's in the trunk. Or if anyone knows of a shop in the metropolitan Chicago area who will do the big 3 for me? Thanks for the help.
