Ok, I'm going to try and decipher and answer this the best I can without any pics. The wire "loop" or "catch" is the easiest part, there are only 2 bolts that attach it, so that should be the easiest to figure out. The latching mechanism is held in place by 2 bolts, iirc, and attaches to the boxed area where you'd expect it to. I believe there is a flat "rod" that goes from the mechanism to the lock cylinder. The lock cylinder is held to the body with a clip.
I need to get out to my car and replace the wire catch, maybe I'll get to that today. If I do I'll try to get a few pics to illustrate all of this.
