Gearhead, it's really pretty easy. First, use a high quality battery box (mine is a plastic Moroso from Summit, $100). It's a vented box with a 1/2" tube to the outside for ventilation. I used a #2 positive cable running through the door sill area from the trunk area to the passenger side of the engine compartment. Since I ran this cable through the interior area, I put it through a heater hose for additional insulation in the interior/doorsill area.

Now for the most important part. Run another #2 cable from the trunk battery neg. ground termial of the battery straight to the engine compartment in the driver side door sill area and along the fire wall straight to the bolt that holds the starter motor. This will assure you of full voltage when cranking. You can't rely on a chassis ground for good cranking performance.

Can't think of much more to say. These are the main points that I remember from putting my battery in the trunk several years ago.
