You should update your description to include something like "also e30 BMW 3 series pin and socket connectors for housing numbers c404 and c405" because they are known to fail and I spent more time than I would have liked every step of the way. This video helped me figure out what I needed to do before I wasted the small bit of wire I'm working with. It sure beats the handycam YouTube how tos from when I last was fixing cars 20 years ago. This video was extremely helpful.

Edit: I can't punctuation.

A helpful video. I'd like to add a couple comments that may be useful to others. In the video, you stress the importance of placing the tool properly during the initial wire crimp so as not to bend the adjacent section of the terminal. To do that, the tool has to fit between the two tabs. The distance available on the terminal is .150". The body on my IWiss crimping tool is .160", so it just isn't possible. I spent a lot of time trying, and your video helped me pinpoint the problem. The insulation on my 18AWG wire seemed larger diameter than the terminal was designed for, and I was getting a poor crimp on the insulation anyway, so I ended up snipping off the section of the terminal with the insulation crimp and just relying on the wire crimp for strength. Now I can position the tool so that it only crimps the intended area, and the terminals pop right into the plastic housing. (Alternately, one could machine down the tool body to something smaller than .150".)
The other thing I'd like to add is that there is a proper ( and improper) orientation for the terminals when sliding them in. Nobody seems to have mentioned that, but it makes a difference. It's easy to see once you look closely.
Let me also add that this is all taking place on Molex Minifit Jr. connectors. I don't know if it's an issue on larger Molex connectors.

Super clear instruction. It helped tremendously for me crimping & install pins into a Molex 31067-1071 clip. Thank you

[SteveJonespilot]

You make this look so easy.. I've never been good at this, but I'm going to give it another shot with your technique!

Thanks for taking the time to create this video

[opexwells]

Really appreciate for posting the video, I learn something from you here.

[mikemckeon]

Great video, one of the few that are in excellent focus! Thank you!

[hotburnymustard]

Thanks for the tips! I forgot that the female looking boxy crimps go in the male connector and the male looking crimps go in the female connector. Great tip for trimming for 22ga...

[Stratocruizer]

Great, detailed instructions with professional "tips". Thanks

[TimStevens]

Old video I know, but very helpful. Thank you!

[markcummings]

Best detailed video I’ve seen for how to crimp those pins. Do you have a video on removing the female pins. I can’t seem to find the right tool anywhere.

[Rockettman]

Thanks for the tutorial. I see you, too, suffer from the terribly painful affliction of cracked dry skin on the edge of the thumbs (usually in winter)!

Once you put it in the connector, is there any way to pull it out or is it stuck inside permanently ?

[SonomaComa]

Is the Molex Crimper the same as an Open Barrel Crimper?

[mannyfilmsinc]

Great video, could you list the part numbers

[haridaliparthi]

I have a male pin got pushed during female joint. I dont have access to the wires on back. Is there is anyway/tool to pull the male pin to proper location?

Any good tips on doing cathode pins? Can't seem to get them to work.
