I just purchased RC 550's and the clips. I was getting ready to start soldering the clips in untill i realized that the clip's wires are both black, there is no sign of which one is positive and which one is negative. Does it matter? he did number the clips so i know which ones go where...i just dont know the positive or grounds to connect them to the injector harness on my existing wiring harness. thanks guys
