4. Slide a piece of the red tubing
over the ends of the red wire of the battery connector. Join the red
wire from the fan to the red wire of the battery connector by twisting
the metal strands together. Slide the red tube over the twisted wires
so that they are covered.
5 . Slide a piece of the thin red tube over the two
black wires. Connect these wires to the switch by
poking the metal strands through the small holes
in the terminals of the switch. Slide the red tubes
over each terminal to hold the wires in place.
6. Insert the four 50mm screws through the holes in the base
plate then attach a nut to each screw to hold the screws in place.
Attach a second nut to each screw as shown in this diagram.
