I need the experts to help me a bit cause I do not want to make a mistake. I have just purchased a spot light harness from aliexpress and it arrived but there are no instructions attached. Please see the picture below, my question is where will the red wire next to Diagram 1 (Where it says LINK THE POSTIVE WIRE) be connected. By the way I already have a fuse box which gets the live + (HOT) from a switched light, so when I attach any auxliary lights etc, they will be on only when the engine is ON.
