MOTM

I'm with Dave on this.  The solder-less approach, while "correct",  is 
better suited to a mass production assembly line that warrants purchase 
of the expensive tools and exactly correct wire (see Paul Schreiber's 
post on this).  Making these by assembly line will go much faster this 
way.  But for DIY the connections are easily soldered, being careful not 
to melt the plastic connector too much.  It takes a little skill, but 
heck, this is DIY.  Soldering works for any size of wire, although 
choice of a gauge (#18 or #20) that fits the pin is best.  #18 wire is 
overkill unless you're making a long cable.  Use stranded wire for 
flexibility.

My technique is to hold the header in a tiny vise, tin the wire, and 
push it carefully into the pin with a small screwdriver.  Then make a 
good solder joint that properly heats both the wire and the pin with the 
solder applied to the work (not just to the soldering iron).  I've never 
had any problems.
