The only sure way is to be able to see the markings on the pcb. Can you post a picture and/or a link to the specific pixels.

I have some of the same strings.


On the pixel, there is a chip on either side of the pcb. On the side with the smaller chip, where the wires are soldered, with a magnifying glass you can see the markings on the PCB 12V DI GND

Just be sure to check your leds to confirm

I have the same strings, no color wires. I had to look carefully the PCB and follow cables just to be sure what was the + & -. DI is for sure the cable in the middle.
