NSS harness carnage!

Joe - I need the whole enchilada....not just the pigtail connector (my whole harness from NSS switch to this connector is basically toast....from this connector to the bulkhead is still good) so....

I got this in the mail today, whole new harness which is great, exactly what I need...except I need to disconnect it at this section. My old harness connector (female bottom section) just pulled apart from the male section....the new one seems like it's "snapped" together, it wont just pull apart. Any ideas? From the outside the connectors look identical old vs new! Not sure how this connector comes apart??? Driving me crazy! The one end I need (left side) is exactly what I need to plug into my existing right side going to my bulk-head and is still in good shape. New right side is not, cause I had to order the E body version to get the correct section I need all in one piece. I thought I'd be able to just pull it apart (like my old one) and just push it onto my existing section! How do I get this thing apart to avoid splicing the good wires into this old connector (bottom)??
