Hi every body I was wondering if anyone in this forum could help me out . I am needing to know the colour off wire which is in the C block ( blue one in Quad lock ) as I had a S*it load off cables and earth's in my double din and got advice to cut them back to one earth but in the confusion I think I have misplaced one wire which would come out off C block #5 and go to C block #7 as the Bose pin . #5 is K-line on Symphony cheers
