This doesn't look right, unless I'm wrong!
Please view attached image. I have this exact same setup with the exact same products.
I need to extend those blue and red power wires from each strand of 25 LED pixels, because the female DC jack that is connected to the 5 VDC 10A power supply is at the bottom of the tv so it's quite far from the end of each strand. Distance of each blue/red wire that I need varies from 37inch to 117inch since they will be fixed on the edge of the frame that will support the LED pixels.
On those blue/red power wires, it's marked 22 awg, 300v, 80 degreees Celcius. With that information, I'm still now sure what type of wires to get and what other technical information I need to get the correct wires.
Thanks for your help
