My friend gave me a set of HID's for my Cobra. There are 2 wires that need to be spliced into the harness of the car. He said that he just plugged the wires into the factory plug. He said there is no need to cut into the factory harness. Does anybody know where to put them? If I plug them in wrong will it cause a nasty short that will cause my car to horoshima? Any input would be great!
