Works very well....

Not after market, just rewiring the aux fan wires through a relay and then to a switch inside the cabin. I used the center vent, which my car has 3 spaces, but only uses 2, so I moved the switch on the far right to the center and added in a switch for the fan. I used a rear dome light switch and just flipped it upside down to avoid confusion, although the rear dome light switch is actually on the driver side vent.
