-2. Cut the cables from the 8 pin connector to 4 inches and remove the tip of the plastic protective cover, also remove the dark purple lead, cut the black and red 26 AWG cables at 3 inches and remove the plastic cover from the tips as well. Place a female crimp pin in each cable one at the time and use the crimping tool following the instructions [here](https://www.pololu.com/product/1928). For the grey and red cables, crimp the black and red 26 AWG cables with them respectively; as shown in the picture below.
