The front ground point is on the driver's side, inboard of the A/C
receiver/dryer, behind the head light.  Another on the passenger side behind headlight.
There should be a 10mm bolt with 3 or 4 grounds attached.

The rear ground is in the cargo area, driver's side about mid-way between
the tail lights and the license plate.  This one is about the same (10mm
bolt and 3 or 4 grounds) as the front ground point. You need to lift the
carpet to find this one.
