2010 c300 my wire harness has 9 wires. I found 2013 wire harness from junk yard and i took it to do a 2010 facelift headlights conversion. Can you help me. Also do i need resistors to not have any codes. My 2010 had fog lights. Where do i connect the new led lights too and my new face lift bumper i do not have the left and right marker lights. Need help with wiring to get everything working with no codes.
