No idea what size wire you are needing to run, but when I ran 4GA in my 92' Cutlass Ciera (similar car, I think), I was unable to locate a preexisting location "I" felt was good, so I drilled my own and used a grommet.
"I" wouldn't recommend running wire anywhere near the gas or brake pedals in the unlikely event it somehow interferes with them at any point.
Also, they make side post adapters for such applications so you don't have to buy a new dual post battery if your current battery isn't in need of replacement.
, though there are others as well. Mine is made by Streetwires, but it'* a discontinued model I bought back in 2004 for when I had my old Corsica on the road.
Best of luck.
