4 wires could either mean standard RGB (one wire for each color and one for gnd or Vcc) or APA102 style addressable LEDs (data, clock, Vcc, gnd). Since it looks like you only have the option of controlling all the LEDs at one time I'm guessing the former. APA102 are much more expensive than standard RGB so it's unlikely they would be used for a product that didn't need their addressable nature.
