I disagree with the above post only in one aspect - I peel back the shielding as outlined above, but instead of soldering a piece of copper wire and risking melting through the inner insulation layer, I simply wrap the grounding wire around the shielding then use a piece of shrink wrap over it to keep the grounding wire from slipping off the shielding. No solder, no heat, no way of compromising the inner insulation layer. Otherwise the above post is great advice.
