For the knowlege base:
The rear latch is actually part of the license plate holder. This is little more than a plastic plate with a spring loaded hinge (gate latch) on the back. Attached to the latch is a metal rod that attaches to gate latch mechanism. Pull up on the latch, the rod pivots on the hinge, the hatch opens, the spring retracts the rod.
To get it out you remove the inner hatch trim cover. Remove the ten bolts or so that hold the reflector panels on the back of the van. Be careful nor to break them off. Remove the reflectors. Then unbolt the license plate cover and detach the rod from the latch mechanism. Take it out, put the new one in and reassemble.
I learned all this through trial and error tearing up a salvage villager at Pull a Part yesterday. Tear up THEIR junker, not your vehicle.
