injectors

Spent a couple of hours at the pull-a-part today and scored a set of free injectors from a mid 90s lincoln town car. black bodies/orange tops that i believe are 19#. will these be ok in my 99 4.0? if not what color to look for?

First, I think those injectors you scored are EV1 connectors, and I believe the 99-01 XJs are EV6.

Here is a short list of Ford injectors, and I think you want the lavender or pink top EV6:

12's - Gold top
14's - Blue Top - E3EE-BA ( Low Impedance )
14's - Gray top -
16's - Blue - E43E-AC ( Low Impedance )
17's - Creme/white top ( Low Impedance )
19's - White - E6EE-AB ( Low Impedance )
19's - Orange/Yellow top -
19's - Gold
19's - Yellow/Black
21's - Lavender - ( EV6 )
22's - Pink top ( EV6 )
