11. An electrical connector as in claim 10 wherein the terminal receiving areas are aligned in two rows with lateral ends of the rows having the first housing member with general one-half cross shapes.
12. An electrical connector as in claim 9 wherein each aperture has two of the lead-in surfaces formed by the first housing member and two of the lead-in surfaces formed by the second housing member.
13. An electrical connector as in claim 9 wherein the second housing member comprises testing holes in a front face of the second housing member into respective ones of the terminal receiving channels.
14. An electrical connector as in claim 9 wherein the terminal receiving channels comprise a second row of the terminal receiving channels which are substantially a mirror image of the first row.
15. An electrical connector as in claim 9 wherein the TPA feature comprises blocking portions on the second housing member being adapted to be positioned in a gap between the snap-lock latches and another portion of the first housing member when the second housing member is moved from a forward unlocked position to a rearward locked position.
16. An electrical connector comprising:
a plurality of electrical terminals; and
a housing having the electrical terminals connected thereto, wherein the housing comprises a first housing member and a second housing member movably connected to the first housing member, wherein the first housing member comprises terminal receiving areas and snap-lock latches which lock the terminals in the terminal receiving areas, wherein the first and second housing members form a terminal position assurance feature, wherein the terminal receiving areas comprise a first row of the terminal receiving channels with a first one of the terminal receiving channels and a second one of the terminal receiving channels being separated from each other by a wall of the first housing member and the first housing member having a substantially open wall area between a third one of the terminal receiving channels and the second terminal receiving channel, wherein the second housing member is adapted to at least partially close the open wall area, wherein portions of the first and second housing members form contact lead-in surfaces to apertures into the terminal receiving channels at a front end of the housing, wherein the front end of the housing is adapted to mate with a mating electrical connector, and wherein at least one of the portions of the first and second housing members have a general cross-shape when viewed from the front end.
