Grounding points 1998 Transport

Can someone help me find the grounding points on my 1998 Transport? I've pulled up the carpet on both sides by the sliding doors but don't see any wires at all. Anywhere else I can look?

Not sure what grounding point you are looking for, but I had a lot of problems that stemmed from the one that is located on the pass. side fender, just to left of battery. I relaced the terminal with a heavy duty household lug with larger selftapping screw and solved problems.
