Ok here is a power injection question.......... I have brought 4 core 14/020 security cable I intend on injecting every 2 strips (WS2811's) call me daft or whatever but im using 3 core plugs (1 data 1 12v 1ground) im using rays "T" 3 core plugs so I can inject between strips 2 & 3, Now on the power injection, Will I solder all for wires from the security cable to I wire from the pigtail that I will be using for power injection? I am using a P12 and this for the power supply (350W Dual Output Switching Power Supply;88 ~ 264VAC input;12V/350W output, CE and ROHS approved) Please help me! Im no electrician! Am I doing this correctly? Or is there something that I have missed etc? Your help/comments are appreciated.
