7 Way Diagram to Use for Rewiring 7-Way on Trailer

Question

Question:

Hi. I replaced my 7 way plug on my trailer. The plug had the colors listed inside. I placed them where the colors were listed. All lights did work, but now my left side blinker/brake does not work. Help. Do I follow the colors inside the plug or by a diagram? Thanks,
