[title] Extend the wiring harness
[* icon_note] The wiring harness - aka ''whip'' - coming from the effector should have four pairs of wires and one set of four wires (from the extruder stepper motor). You will extend all of these wires using the extra wires and heat shrink in the ''Extruder Extensions'' bag.
[* red] First, gather all of the wires in the whip and clip them all to the length of the shorter wire so they are all the same length as shown in the first photo.
[* red] '''Parts cooling fan wires extension:''' clip off the white connector (should still have a knot near the end too) and strip 8mm (5/16") of insulation from the wire ends. Locate one pair of the ''26/2 Cable Pre-Terminated'' wires and shorten it from the male "pin" end by ....
[* red] '''Hot end cooling fan wires extension:''' clip off the black connector (should still have a knot near the end too) and strip 8mm (5/16") of insulation from the wire ends. Locate one pair of the ''26/2 Cable Pre-Terminated'' wires and shorten it from the male "pin" end by ....
[* red] '''Thermistor wires extension:''' clip off the black connector (there should not be a knot near the end) and strip 8mm (5/16") of insulation from the wire ends. Locate one pair of the ''26/2 Cable Pre-Terminated'' wires and shorten it from the male "pin" end by ....
[* red] '''Cartridge heater wires extension:''' strip 8mm (5/16") of insulation from the wire ends (the larger pair of blue wires). Extend with the pair of red ''18 AWG Silicone Wires'' using the two pieces of ''3/32" Heat Shrink'' to insulate them.
[* red] '''Stepper motor wires extension:''' clip off the white connector and strip 8mm (5/16") of insulation from the four wire ends. Locate two pairs of the ''26/2 Cable Pre-Terminated'' wires and shorten them from the male "pin" end by .... Label one pair '''A''' and the other pair '''B''' near the connectors with marking tape.
[* red] Solder and insulate the each wire as shown in the second photo: black stepper wire to the black wire in the '''A''' pair. Brown stepper wire to the red wire in the '''A''' pair. Yellow stepper wire to the black wire in the '''B''' pair. Orange stepper wire to the red wire in the '''B''' pair.
