Immediately after you go through checkpoint 6, keep following the trail. You will see a bridge once you go down the hill. Go over the bridge. To the right is a fenced in area with a oil tanker truck in front of the entrance. This is immediately before you go through checkpoint 7. The cash box is over to the right side of the fenced in area.
