Dimming-only mirrors, including wiring pigtail & mounting button.
The OE Bronco dimming mirror (used VERY rarely in F-series) is a 119 (F4TZ17700A) with a special 3-pin connector; not the 7-pin shown above. The button glows green when pushed up (ON). And the 119 is 13" wide instead of the normal 11".
