My 2008 Altima has crashed. Repairing the headlight wiring. Part 8

In one of the worst issues resulting from the crash, many wires in the wiring loom to the headlights and associated front lights were severed. I've got to figure out this mess and solder them back together. It didn't seem too bad at first, but I ended up with only one low beam and one high beam working. In trying to figure this out, I find out that each headlight bulb has its own fuse. I also learn that there is a positive battery terminal fusible link that figures into the whole mess. In the end, I had to take it to a professional to find out the problem. I probably could have found it myself it I had spent enough time fishing around in the entire car, because the problem was on the other side, not at the area of impact.
