Ok, I was about to shell out some money on these harnesses:

Question though. How exactly do heavy duty harnesses work? These things look like a small extension cable or something. If they're supposed to prevent too much voltage from frying your stock harness, but that voltage still has to go through your stock harness to go through the heavy duty harness (attached to the end of your stock harness) how is that helping? Or are these meant to completely replace the stock harnesses?
