best way is goin through the wheel well. youll have to take off teh drivers side wheel and well liner to get to it.

I just did this last night on my '95 LE.
The wheel well liner was easy to remove. Once it's out you can access the hole/boot that the hood release cable (and some other bundle) goes thru. There's plenty of room thru there to route a power cable, and there's an easy access opening from the engine bay to get down to the wheel well.
I used an ice pick to puncture a hole thru the boot from the wheel well side, then ran a long stiff wire back thru from inside the passenger compartment, taped my power cable to it and pulled it back thru. You have to punch thru both sides of the boot. Kind of like puncturing a rubber ball all the way thru.
You can find the location inside the passenger compartment by following the hood release cable up to where it goes thru the firewall.
Once you've got the wire into the passenger compartment, you can remove the plastic door sill covers, and the plastic panel that covers the drivers seat belt retractor, take out the back seat cushion and easily route the wire under the carpeting all the way back to the trunk.
Sorry, I didn't take any pictures. I saw a thread the other day though where somebody had posted some good pictures of what I just described. I can't find it now though.
