Crimping tool?

Molex 63811-1000 Service Grade Hand Crimping Tool is the Cadillac. But this or similar would do the job if you only have a few connections:

If you’re looking for inexpensive you may have a hard time with this. The crimper shown above will mangle those terms. I have a drawer full of these types for Amphenol, Molex and other aerospace pins but that doesn’t help. Have you looked online for electronics surplus sales? Sometimes they have this type of stuff “used”.

Try this link and see if you think it’s worth the chance. If you’re careful you might be able to pull it off! They’re in Los Angeles but I think they can ship- good luck!
