This is works on the Camaros that has the headlights with the factory daytime running lights. With this harness your Daytime Running Lights will become Fog Lights by staying on anytime you turn on your parking lights ( during the day your DRL will still function as they currently do). So you can finally drive around with Factory Halos and Fog Lights on. Harness is plug and play with factory male and female connectors (so just plugs in line). Harness includes inline diodes ( only allows power to flow in one direction (( like a check valve)) ) to prevent any feedback to system computer.
