I agree,  It does take some talent to get them installed well.
t helps a lot to have the correct tools.  I do not trust myself to  
rimp them
roperly so I carefully fold the insulation tabs and solder the pins.
I have heard other folks giving up on the Molex connectors completely  
nd
hanging them out to RCA phono and WECo 310 TRS jacks and 303 TS Jacks.
owever you must not leave any open holes, less the mice get inside...
In most cases patience is a virtue.

A quick piece of advice on ordering Molex, or other crimp terminal  
ystems
hat you don't "normally stock"" If you weren't planning on just  
uying a std
ized bag of pins for them, then ALWAYS get at least a FEW spare pins  
han
ou require!
My rule of thumb is to order at least TWO extra pins per housing  
rdered.
hat should more than cover most possible errors, or needed rework.
This is because those cheap swaged pins have quite a number of failure  
odes:
) A percentage of the pins in any batch WILL be bad (misformed/ 
rushed/badtabs/etc)
) Crimping failures - (in the tool wrong, weak crimp, excessive force  
reaks pin, etc.)
) Failure of a crimped pin to properly lock into the housing (tabs  
reak, etc.)
) Wire pulled out, and you can't recrimp it.
) The pin didn't survive when removed from the housing (ex: you stuck  
he pin
n the wrong hole, and the fragile pin or its lock tabs didn't survive  
ebending... Grrr...)
Of course, once your "spare pin inventory" starts going up you can  
lways
all back to just ordering what you need. But until that time (or if  
ou're
rdering a new kind of connector for the very first time) I'd always at
east add a few extra pins to each order.
I'm an "occasional crimper", that doesn't do it daily.  I find having  
t least
 FEW spare pins to trash also gives me a chance to get a "feel" for
rimping THIS batch or class of pins with some scrap wire, BEFORE  
tarting
o crimp the real wires (but don't use up ALL of your spares during  
ractice!).
t may take a ruined pin or two to "get back into the rhythm" of it,  
ut a
ew "practice pins" easily allows you to find the minimum and maximum
and force to apply, to insure good crimps.
This avoids my Worst Case Scenario: Finding out after all the crimping  
s done
hat you are just ONE pin short, and you now must spend $10 or more  
or a
in order (parts and shipping) just to get that one, lousy, few cent  
art... <AUGH!>
Good luck!

 I do not have a lot of different types of Molex so some might need to
 be ordered. We will see... at least the price is right.... postage  
 only.
