Personally I don't reuse (or even use) braid. I've found it's better to just use wire. Less chance of a short.
Pictures, pictures and more pictures. On my first couple swaps I took a thousand pictures from every angle. Later I realized I actually had to look back on about 3.
It's actually much easier than it looks. Things come off in layers and the harness keeps the shape. Lift it off the old playfield and lay it on the new.
