Window-mounted solder fume extractor (not just for RVs!)

Step 6 Connect fan to power cord

Make a hole in the metal vent tubing just inside the window panel to pass the cord through. Put a rubber or plastic grommet in the hole to keep the cord from getting cut (or use hot-melt glue after you put the cord through). Solder or crimp-connect a cord to the fan terminals (make sure to pass the wires through first if you're crimping!) and stick the cord through the hole.
