Running LED turn signals in your C5 without additional resistors triggers hyper-flashing turn signals due to low current draw. This can be remedied by adding load-resistors (included at no additional cost with our switchbacks), but these get hot and permanently splice into the factory wiring.
This harness installs under the dash and provides a plug & play way to correct this issue and restore a normal flash rate without the complexity and hazards of resistors. Being plug & play, this is 100% reversible if you decide to put the car back to stock at a later date.
