Help with wecan/xlp duo wiring

[sheriffmedic95]

I have a four wire xlp inner edge Lightbar (red black green gray). I just got the wecan module and have never messed with one before and having difficulties with the wiring. The wecan module has red + black - and I wired the green and gray to the green and gray going to the inner edge. There is another black/white wire I’m unsure what to do with. I then hooked the red + and black - from the inner edge then tried Hooking up the pattern wires and got no power to the light. What am I doing wrong?
