10 Pairs 3pin JST SM Female/Male Connectors 15cm 22AWG Wire for WS2812B WS2812 WS2811 SK6812 LED Strip Light

No, the corners on mine are all right angles. I got two of these. Then I got two of the BTF CCT controllers (two-pack with the remote, one for each cabinet) and I wired them to these connectors - Green into Warm White, White into Cold White (although I tried the other way and that worked too) and Red into the inner V+ terminal. Then I got these splitters so I could connect both the top and bottom LEDs into a single controller. As for the power supply, I used the one that came with the cabinets. I simply unplugged them from the built in controller and plugged them into the BTFs. Remote was pretty easy to pair, and the wireless gateway wasn't hard either once I figured it out. I have the occasional glitch where it will randomly switch to cold white or default to it when I turn it on or randomly switch, but for the most part it works great.
