Hacking a Canon off-shoe flash cord part 2

The thing to notice in this post, apart from the photos, is the way the copper shield is wrapped not only around the main bundle of wires but specifically around the red wire. This means a "delicate" signal is coming down that - either that or a really strong one that would interfere with signals on other wires. The twisting of the wires in an ethernet cord also works as shielding: it is important to route the red and ground shield together as a twisted pair though. I chose the blue-wh/blue pair.

The plastic shield (bottom right) kept the wires out of the locking assembly (silver bit). It is no longer needed and also in the way.
