Do a search on "Big 3". You will find step by step info on how to complete it. Some have even posted pictures of how its done.
Good luck,

The Big 4 are
1. 1/0 G from the battery to the alternator (in parallel with the OEM wires) with a 300amp in-line fuse (don't forget this!).
2. 1/0 G from the Battery to the frame.
3. 1/0 G from the engine block to the frame
4. 1/0 G from the Battery to the chassis
