Crimp or solder shields

According to the "Acceptable Methods" manual (I can never remember the AC
number), the disadvatage of a wire solder joint is that it might break due to
vibration fatigue, but it is never acceptable to add connectors to extend wire.
I would solder the wire to the shield.

Soldering is a very bad way to go in high vibration environments. I lost my
alternator due to an improper repair (solder rather than crimped connector).
Vibrations eventually broke the strands. Soldered connections are very
brittle.

I would use crimp as much as possible. As has already been stated,
solder cracks under vibration and will eventually fail.
