Help ID chewed wires in engine bay

[d3kyler]

My grand father recently passed and left me his 2006 Mustang. There are a few chewed wires in the engine bay from field mice. Does anyone know what these may be & if id be fine to just solder them back together or be better off buying a whole pigtail? Any help is greatly appreciated, all I've found so far is the yellow wires may be for the Knock Sensors, but I have no clue about the black wires. Thank you in advance!

These wires are on the left side of the engine bay (facing the front of the car).

UPDATE: I believe the yellow wires to be for the knock sensor, and I now believe the black wires go to the camshaft position sensor. Will update whenever I fix this & let yall know if I was wrong or right.

Suggested repair is always to rplace the pigtail. Howver if not available and you are comfortable with a solder iron, have at it.
