So you are talking about the wiring going to the coil/ignition module or the spark plug wires on top of the coil housing? If you are talking about the smaller wires at the base of the coil pack this will be the main engine wiring harness there is no sub harness for this. Here are how the wiring go to the module so you can get an idea of which wires go where. Check out the images (below). Please upload an image or a short video in your response, so I can see what's going on.
