I am looking for 5-pin L shaped connectors but cant seem to find any. I see a ton for 4 pin, but I have an RGBW strip for the project I am working on. Trying to avoid the tediousness of soldering a ton of strip pieces together.
I ran into the same issue, and ended up using these: http://www.amazon.com/gp/product/B00ML2IVUG/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1
It may not work for you depending on what you are trying to do. I was able to hide the extra wires that these provide. Keep in mind, if you have the water proof version of strip lights, you will need to shave off the water proof coating to get these to work.
