The clips for the 211-2 style tubular bulb are molded into the housing:
Depending on how late your car was made, it may have holes but no clips inserted:
Or just be molded flat with no space for a bulb at all:
In addition, you need the clear lens, F6DZ-13734-AA:
Another forum's user posted that on his early 97 door harness it still had the wiring plug for the door panel light up near the corner sail, he just needed the bulb clips and their wiring off another door (and lens).
The bulb wire connector face is not listed in the EVTM. The longest end of the correct harness will have four connectors (an additional two for illuminated entry and door lock switch). Instead, just splice in any two-wire plug pigtail if you're not going to get a complete 96 door harness and panel. In the door you need black (ground) and the light's power.
If you are looking at 96 doors with everything, you might as well just get the whole door panel and door harness - even go crazy and get a handle with the switch (dunno if later GEM modules will understand the door switch though). Then you just need to add the pin(s) on the car side of the door plug.
In another Taurus forum, look at the post "adding circuits to door jamb" to see how to add back the missing wire (or see if you've still got it).
