+ strip one side only 1/8 inch.
+ strip the other side about 1/4 inch.])
+ (item [use the end of the wire stripper to bend a hook in the wire.
+ make this hook on the side of the wire with a smaller
+ exposed section.])
+ (item [do not bend the wire so that the exposed wire runs alongside
+ the sheath.])
+ (item [put the hooks through the tabs on the motor.
+ make sure to place the green and yellow wire on the
+ correct side of the motor.
+ match the side of the motor that already has wires
+ attached.
+ wrap the rest of the wire around the motor in order to
+ keep the wire from falling off.])
+ (item [once the wire is in place, wrap solder around the motor tab
+ and wire.
+ heat up the solder, motor tab and wire with the
+ soldering iron.])
+ (item [test the solder joint with the 9v battery.
+ touch the battery leads to the motor leads.
+ make sure the 9v battery is on.
+ if the motor moves, the solder joint is good!])
+ (item [get section of electrical tape, roughly 100mm
+ (about 4 inches).
+ slide the middle of the tape under the wires.
+ this tape will keep the solder joints away from the
+ metal band around the motor.])
+ (item [the zip tie will hold the wires to the motor.
+ wrap the zip tie on the round part of the motor where
+ it meets the square portion of the motor.
+ this will provide mechanical support for the solder
+ joints.
+ once the zip tie is wrapped, use wire strippers to cut
+ off the excess zip tie.])
+ (item [cover the solder joint with hot glue.
+ this will further keep the solder joints from corroding
+ in the air's moisture.
+ it will also keep the joint safe from anything poking
+ in.]))
