A relay harness helps draw current for your hid's directly from the battery, rather than through your factory harness which wasn't designed to power hid's. A relay harness shouldn't affect your hid's in any negative way, in other words if they're working fine, by adding a harness it shouldn't get any worse. there's a pic attached how to connect a harness, but you can google it to find more pics and installation instructions.
