The dual level charge cable case goes there, On. I think you should have two tow eye bolts (Chevy calls them Recovery Hook Front, Recovery Hook Rear standard all trims), looks like you have just one?
Note for 3LT, 3RS buyers, the tire inflator kit components to the right of the tow eye bolt will not be included as you'll have self-sealing tires.
The rear seat slits are for the locking latch. The sewing looks like it could be better. Compare it to what the dealer has on the lot., Equinox EV or the Blazer EV.
