If you install your HID kit and they do not turn on you may have reverse polarity. This means the power and ground wires on your vehicle's harness are reversed. What you will have to do is plug the harness connector into the ballast backwards. You will be plugging in the connector from your car into the kit backwards. This will not harm the vehicle or the kit.

Note: Reverse Polarity is an issue with the cars wiring not the HID kit. Some cars come from the factory wired in an orientation that is reversed when compared to the HID kit. When using stock halogen bulbs, polarity has no effect, therefore, some manufactures will have the power and ground wires opposite of the HID kit. Some manufactures will have reverse polarity more then others. A lot of Chevy's (Silverados) and Chrysler's have reverse polarity.
