I just received my RGBW led strips and they have 5 wires but my H801 has 4 ports on each sides. I assume the 5 wires are RGB+ 2 for power (+ and Gnd). How can I find out which wire is for what connection? Also, how to connect H801 to led and power. Can someone please help me with the wiring diagram/tutorial? Really need to understand so that I can tell my electrician the schematics on how to wire it over my ceiling.
