Sleeve Preparation and Installation
With the pins removed we are nearly ready to apply the sleeve, sometimes the connection pins can be a real pain and are renowned for catching on the inside of sleeve. To counter this, apply a small amount of thin sticky tape tightly around the pin, giving it a smoother surface.
Measure your cables taking note of each length, when cutting I usually add a few mm to the length just to be positive it will reach. Try to use the sharpest blade or scissors you have at your disposal, this will ensure a cleaner cut and in turn make the heat shrink fit a lot easier. I like to use my wife's dressmaking scissors - don't tell her, though! Cut only enough sleeve to do the cables your planning on sleeving otherwise you run the risk of the cut ends fraying badly before getting a chance to use them.
Take your cable and feed the wire down the inside of the sleeve - if using Paracord you will first have to remove the core strings, obviously. Use a push pull motion, pushing the wire and pulling the sleeve until the sleeve is completely covering the length of the wire.
There is also a really clever way of using the inner core of Paracord to almost auto sleeve single cables. Remove all but one of the inner strings from the length of Paracord, and then tie the remaining string to the end of your cable. Holding the insert end of the Paracord as well as the opposite end of the string, gently pull the string through the inner sleeve hopefully bringing the cable through behind it. This method will only work with taped off pins, because it's guaranteed if you have any jaggy bits, they will catch.
