I'd like to help but honestly, looks like an adapter to a off brand dell electronics Wi-Fi connection. Any more information on the unit?
I'd take it out, and take the cover off, and see what's in it. If you do that and post some more pictures, maybe we could help.
Trace the wires. My guess is that you'll find they go to the stepper motors that control the vents. The box takes the switch position (floor, defrost, vent) and signals the motor to move to that position.
