Don't waste the money on a kit. You can buy the same battery box @ Autozone for 10 bucks (it's not that impressive anyway and I couldn't use half the stuff that came with the kit). All the connections you can get at Autozone or Home Depot. The wire is only 2 ga. in kits and very stiff. I went and bought 1 ga. welder's cable at a welder's supply. It's a little more expensive, but more cunductors (the more wires = more surface area of wire - the electrons travel on the surface of wire, so this is advantageous) and softer or more bendable). I then went and got some clear plastic tubing at Home Depot and slid it over the cable (with the help of some vegetable oil as lubricant). This tubing added protection since I decided to run the cable underneath the car. I used existing drain plugs (in spare tire depression for positive and trunk for ground) to go from the trunk to the engine bay and cable tied the cable to the fuel lines going forward. As far as croosing the engine bay, I just brought it up and across right at the cowl and on around to where the battery was. I used a gray PVC box from Home Depot that has a screw down lid and had all my cables go into it and made all my connections inside of the box. About 5 hours start to finish. Can get picts if you'd like.
