How to re-use Philips Hue Lightstrip Plus cut offs

I had a couple of cut offs from a Philips Hue Lightstrip Plus and rather than spend £20 on another extension, I had a go at soldering on a connector and making the cut offs usable. This shows what I did and if it worked. (Spoiler, it did). The connectors are "40 Pin 2.0mm Pitch Single Row PCB Pin Headers ST" but all you need is 6 Pin - however the pitch is the important bit.
