Where exactly under the driver's seat is ground 301!

[coastal ranger]

 I'm having some major wiring issues in my 2010 ranger. Seems like the previous owner really trashed it and flooded it . Rust everywhere! I'm trying to clean all the grounds and ground 301 is central to my issue. I won't go into what's going on with it here but in another post. Just need to know where to look. Is it with the wires directly fixed onto the underside of the seat or on the floor? From the little I did find it's on the floor somewhere. Help! I have a 4wd extended cab. 4.0.

This is all they have. I picked a 4wd v6 model
