I found some photos in my collection that might help you out. The first photo (below) shows one of the cables that attaches to the fuse box cover release handle fully assembled (that is the one on the right), and one of the cables partially disassembled (the one on the left).
All that remains to be done with the cable on the left is to slide the cylinder assembly out via the slot that is visible.
Note that it is a tricky job to disassemble these cables. It's not difficult, it's just tricky. The black collar assembly around the end of the cables is a friction fit (a snap-fit) into the circular assembly on the release handle. You just gently push it up and out to get it to the partially disassembled state. It is handy to have a metal pick (as shown) to push it up and out, otherwise, you'll bust your fingernail if you try to do it by hand.
Needless to say, make sure all the plastic parts are warm (room temperature) before taking them apart. Don't try to do the work outside if the vehicle is cold-soaked.
