Unfortunately the ground diagrams are not too good. But there should be a major on that goes from the battery to the starter area, one or two to the drives side fender and one to the intake somewhere. There are also individual ground strap on connecting the hood too.
If you take the battery and tray out you can see most of them.
There usually is a ground that goes to the frame near the battery and on that goes to one of the starter mounting bolts.
There will also be a few smaller ones that will terminate by the shorter cable under the battery. FWIW if you replace the one going to the starter bolt that would be good enough as this is where most of the power will flow and it is secured to the engine block.
