i purchased a plug n play xenon kit and it works fine but i want to install a relay harness to protect the stock wires. i bought a relay harness but after installing them it does not turn on. it works fine when i take it off and reuse the orignal headlight socket then it works. works=using stock headlight socket. not work=reusing relay harness. i installed the relay harness by connecting red positive ring to the red battery side and black ring negative the the negative battery side. i connect the two males socket to the two ballasts and i connect the female socket the the one orignal headlight socket. it just not turning on. any help?
