The dreaded rear light issue

[Kn0bSh0t]

Hey All! I have the dreaded rear light issue. I have tried cleaning tge contacts on the plug and housing. Ive tried the ground wire bypass but im not sure if im doing it right. I split the ground wire before the plug, then connect a new wire to that. Then run a wire and connect it to the (what i think) is the ground rail on the unit. Can someone advise if im using the correct ground pin as per photo. Im pulling my hair out!! Please see attached photo if my housing and the rail im using.
