The Big Three Kit
This is the Big three kit. What this does is get all the possible power out of the stock alt. You get three wires (get it, BIG 3) you get a new 4ga wire from the battery neg to the fender, new 4ga from the alt case to the battery neg, and a new 4ga wire with fuse and fuse holder that goes from the alt to the battery positive. this will help with the dimming headlights or issues when installing a big stereo in your car.
