I just bought a 2007 civic si and something is going on with the the headlights. The driver side has been messed with and when I turn the lights on, the high beam comes on on the drive side but not the low beam while the passenger side is correct. The wires on the driver side is spliced and I just need to know what I need to get to replace them all together. My fiance mentioned an entire new wiring harness. Is that right??
