untwisting the pairs more then needed makes lining them up more difficult. dont untwist all the wires at once (pair by pair)
when you cut the wire back place the cable so that the orange pair is to the left and brown pair to the right. (rotate cable if needed)
next take the pair closes to you (green or blue) pull to you.
Now start with blue pair untwist, keep in the middle, solid blue to the left.
next untwist orange pair, then brown pair.
that leaves green pair, untwist and keep green/wht to the left.. Green will split so that blue is in the middle of the green. straighten these 4 wires together..
now add orange (orange white to the left) and then brown (brown solid far right).... pitch and cut, do not let go, slide ice cube over pitched wire and crimp
always starts with orange/wht and ends solid brown. solids nvr touch, stripes nvr touch
do this way every single time, rarely have an issue.. hope this helps
