Mine came with the wiring and it simply plugs into the existing wiring. They work great....got the 8000k

I had nothing but problems, bulbs and ballast where blowing, Put harnesses on and have not had a problem in over 6 months! I guess the stock wiring dont always give it full power and cuts the life of the ballast for $10 or $15 worth the time and extra cash
