question: where did you get the pins so that they fit into the OEM connector?
and this may be stupid but you know your added wire? if you just tap connect it to the existing ground you prolly did it in the middle somewhere so shouldnt there be some wire left? did you just cut that off? even so isnt there a bare wire endfor the other end of the added ground?
