All of my pigtails were in about the same basic condition.
The insulation near the red plug was coated in black gunk,
which I removed, and all are the faded red you see. The origional
red might be able to be restored with further cleaning and vinyl paint.
I have not delved into the plugs terminals, so a good cleaning with
contact cleaner might be in order. The wires are not lumpy or overly
stiff so I think, if handled gently during install, they should be fine.
