My car is a U.S. regulation 2006 e60 530i, I installed 51,167,065,081 and 51,167,065,082 Mirror glass heated, wide-angle, but found only two sockets on the lens, but after the mirror plug 4, respectively, red, purple, black, brown, 4 line, does the need to connect the lines of what two colors would make my lens heating function, thank you :wacko: :wacko: :wacko:
