Five Minute Fan Guide
As I mentioned earlier, fans are the easiest starting point for new cable sleevers. Most fans only have three wires which can be sleeved individually or with a bit of messing round as a single piece - three wires are the maximum Paracord can contain, for thicker wire bundles keep reading.
After labelling your cables and removing them from the fan housing, you will have to split up the three wires, if glued together. Even if you are sleeving all the wires together they will not fit unless they are split up. Decide whether you want to sleeve all the way to the motor or not, and measure the wires accordingly.
If going with three single sleeved cables, run with the same method as above. But if you're going to sleeve all three as one, you will have to insert the three wires individually, one at a time. I position my three wires so the little barbs are wrapped over the cable with the pins staggered about 15mm apart. When satisfied with the position, I cut one long piece of heat shrink over the pins and shrink it down, compacting the bundle to its tightest form.
Using the push pull method again slowly snake the cable through, it will be a tight fit and will take a lot longer, but it is possible. Keep at it and when it appears out the other side keep going till all the heat shrink is through, and then carefully slice the heat shrink off using your blade. Tape can substitute heat shrink, but tends to make the package a bit thicker and harder to work with.
