Getting a good crimp on the tiny pins used for the trim motor's Molex connector can be problematic ... as a review of past VAF posts will reveal. Fortunately, I had tiny jaws for my crimping tool and have not yet had any issues to this point.
However, that said, should the wiring to that tiny connector ever show the slightest hint of trouble, I absolutely would NOT repair the offending pin(s) and reuse that tiny Molex connector. Instead, I would suggest considering converting to male and female pins used in the DB connectors. After crimping the new DB male/female connector pins in place, mate the pins and slide a piece of TIGHT fitting heat shrink tubing over the pins then shrink ... you will end up with a long lasting trouble free connection that can easily be taken apart later should the trim motor need repair. The heat shrink will shrink down tight around the pins and will prevent them from coming apart on their own. Food for thought.
Happy flying,
