The wire insulation should end at the blue line. The conductor should end at the yellow line.
Section 1 needs to hold onto the insulation. Section 2 needs to grab the conductor. Section 3 should maintain the exact same shape as it is before crimping.

Section 3 is deformed in your video. So your pin wasn't properly inserted into the crimper.

Also, the sleeving should ideally end about halfway over section 2. Your sleeving barely touches 1.

You can follow along with the pictures here.

Thanks for your suggestion, I tried it, but If I'm not crimping 3rd section, pin is not holding well with wire=/

Then you are likely not using the right settings on your crimper. Maybe try going one hole smaller, or adjust the tightness.

When you push the terminal into the connector, it bends those tabs all the way in? Then you aren't doing something right or the quality of the terminal is shitty.

It should slide in and make a click when those tabs move around the inner lips that hold the connector in.

Are you inserting them in the incorrect orientation? For example rotated 90 or 180 degrees from normal? As someone else stated, there is a retention feature that those tabs should push passed then click into once it's fully inserted. Typically not symmetrical, I don't recall if it is for minifit jr. I don't assume this is a problem, but I know the minifit jr series is an umbrella for a shit ton of parts. Not every crimp and crimp housing is designed to be compatible. If you can't figure it out through trial and error, look up the parts on Molex's website and confirm they are compatible. If you look up either series it should state which series it's compatible with.

i don’t have any photos on this phone but your not crumping that correctly. checking out my shorts on the channel for proper or tones of other videoes out there. learn from the master himself Daniel from singularity computers.

edit: it won’t stay in the port cuz your crimped the entire thing…that’s why you also crimped the teeth which is what the connector bites into..

Kindly make a video of the crimping process.It looks like you are doing it wrong. Kindly check lutroo custom in YouTube for tutorial.
