Yep, fan controls for the rear HVAC. Comes in real handy in the summer, put the 2nd row seat ceiling vents facing the front, so it blows on the necks of the front row passengers.
I mounted mine to a bracket I made using Velcro. The bracket is attached to the lower panel using one of the existing screws. It's spaced out with a wine bottle "cork". I also made a shorter cable.
Finally got mine today... came with a suction mount to hang below the rearview mirror... guess i will see how that works, but am guess it will not stay up there very good.
I have a flexible post attached to the front left passenger seat hold down bolt. Holds the control head for my Alinco VHF/UHF amateur radio and the Scan Gauge.
