What do you mean "frail"? Like "charred" because it was burned, like "corroded all to heck?"

Do you have a still camera, or a still mode? If so, use that. The video is too jumpy to help. Also, how about some colors for the wires.

One more try: It appears that in the video at 15 seconds there are approximately five or six wires. Which of those is "frail?"

What are the colors?

If there are six, this is what they go to:

Yellow: +12V for low beam when fuse is good and light is on.
White: +12 V for high beam, ditto
Grey/Green: +12V for fog when low beam fuse is good and fogs are on
Blk/Grn: +12V for right turn signal
Grey/Red: +12V for the running/parking lights
Brown: ground
