I did it on my Subaru wagon!
The mechanism is very similar. If you remove the hatch trim, you can see the latch mechanism. Playing with the outside handle you can see how it pulls on the rod that's connected to the cam that will release the latch. You just need to make a way to create the same movement - usually a cable or another rod. On my Subaru I used ~18" of thin rod and clamped it strategically onto the latch mechanism. I fed the rod through a small hole in the trim/skin of the hatch to the inside cabin area. My rod was threaded, so put a small knob on the end to make it easier to pull. Pulling the rod just so released the latch, and out I went.
