You are going to have to try to go in from the left side and snag the trunk latch lever itself. You might be able to push it from the right side, but that takes a straight shot, and I think pulling the lever would be easier. I'm sure that the job will require some contortions, holding your mouth just right, and numerous cuss words. Take off or loosen as many body panels as you can. After you get it open I'd suggest crimping down the cable once it is in the slot on the lever. You might also consider installing an
Emergency Trunk Release. That will give you a secondary cable (which also needs to be crimped in the slot).
