There is not enough information on this drawing and there is no information on what it is used for as well as if this connector exists from another manufacturer.

Furthermore, the connector has crimp terminals inside of it that need to be spec'd out and whether the crimp terminals are inserted or if they are over-molded. Crimp terminals typically have very detailed tolerances for accuracy and for repeatability.

This is the part that i found on Amazon :

Since this is for a first generation Mercury Cougar, the Ford Mustang will also work as well :
