The 69 front parking lamp assy has the smooth lens & external ground wire w/ ring connector. On most 69 Coug's that I've seen, the ground wire is connected (terminated) on the lamp housing stud, as assembled to the front valance panel. Normally left stud / right parking light & right stud / left parking light; individual grounds terminated on lamp housing studs closest to center of front valance panel.Smooth Lens is 1969, Textured Lens is 1970. They Have different Wiring. One has an External Ground Wire with Ring Tab for Screw. The Other has it Integral with the Plugs. IIRC.
