Eagle libraries for Automotive Header connectors
You can't expect a CAD system to have schematic symbols and footprints for all possible components you might use.

If you can't find the part you want quickly, you should just make it yourself.  If you do this, you will be sure that the symbol matches the actual part you are going to use (I like to have the actual part in my hand when making symbols and footprints.)

As I have found errors in commercial libraries, I always check the actual part, or maker's datasheet) against the symbols I will use - this often takes almost as long as making the symbols myself.
