FYI, the 478 prefix on that part number is just something that Mouser adds. It's the manufacturer code. I'm surprised that you got two different connectors with the same part number. Regardless, either will work. Don't forget to slide the release bar when inserting the terminals.

Well i was "handed" the first part by hand from the ITT representative so technically I didn't order it but their quote stated 9440101, regardless like you said you can do some minor cutting and make to other work. BTW your suggestion for the small terminal 571-2-964286-1 worked great. thanks for all the help.
