Need schematic for connecting specific Arduino Neopixel strand to an Uno

Note that the Amazon link says:-

May or may not include connectors (2 or 3-pin JST) if you get middle piece

Yeah I'm thinking I'm going to just strip it. I'll follow as you said but that's pretty much how I set it up before, besides the fumbling with the connector. I'll update after work if any problems come from it.
