I simply buy this Molex shell at at 27 cents: http://www.digikey.com/product...92032&vendor=900
Then I buy the contacts for it here: http://www.digikey.com/product...1119/WM1103-ND/26390
You can simple fold the contacts over the bare ends of the track connection harness and solder them, most folks don't have the crimp tool.
