I'm doing the same and found that aux outlet with the three prongs on my bike. I'm getting the splitter and power lead. Which wire goes with which? My lights have three wires - black, red (with inline fuse) and green. The Beaver power lead has black, blue and yellow. My instructions say the black is negative, red is positive, green is "+ACC(Power Anti-Loss", whatever the heck that means. I'm going to solder and shrink wrap but want to make sure I do this correctly - black with black, obvious, but what about the other two? Thanks!
