... the direct-to-the-battery lug wasn't introduced until 2001 for model year 2002, so you can't find it because you don't have it.
The emergency cable is not in the driver's wheel well, that's for the 987s, not 986s.
The emergency cable in your car was installed by the factory to end near the right (passenger) headlight.
But the easiest way is to feed 12 volts through the 12 volt socket. It won't pass much current, so don't try to charge it in a few minutes.
Put it in trickle mode and let it charge overnight. In the morning you should be able to open the trunk.
If not, you'll have to find the end of the emergency cable close to the headlight from underneath.
You'll have to undo the bottom screws of the bumper skin so that you can pull the bottom forward and sneak a peek up into the bumper.
Use a flashlight. You're looking for a thin (1/8") braided stainless cable with a loop at the end.
Grab the end with a hook fashioned from a coat hanger or similar and bring it down to your hand.
Once you have it firmly tug the cable towards the right side in one jerk. This should pop the hood.
Happy Boxstering,
