Actuator seems to add complexity. I'm going to guess it is something simple like: "Don't remove the duct plug and wire connector cover in cab mode." If so, I will ignore those instructions. :)

Wouldn't be surprised if the HVAC in the console has big plastic plugs in it. A "remove for four seater option" type deal. And then a year from now we'll get threads about "why don't I have air in the back of my SUV" when people don't remove them!
I do some plumbing. There's a great analog to this. Garbage disposers have a knock out plug by default in the dishwasher inlet. People replace disposers all the time and are then baffled that their dishwasher won't drain .

I'd have assumed it's just a physical door or valve you can open/close manually. No need for actuators and extra firmware/wiring.


I'd also assume you just plug the USB ports into one of those typical USB hubs "upstream" when installing the console.
maybe. the latter certainly sounds like a simple and logical lowcost way of doing things. I'm just not accustomed to seeing that approach in the traditional automotive world.
the former though, seems inefficient; like there'd be HVAC blowing pretty hard right at a plugged spot directly between the seats. certainly will be interesting to see what it looks like we we get our hands on 'em.

Best case scenario, down under the HVAC controls in the dash, there will be a panel we can remove there to hook the console up to. I know from some basic readings into home HVAC that you can cause problems closing vents as that line becomes a dead-pressure zone or something like that and affects the rest of the system.

Still excited to have an easy tunnel to run things through. I do a lot of dashcam work and rear dashcams are a pain in the butt when you have to go through tailgates, side trim, around doors, etc. I can't wait to just fish it through that console!

You might be onto something.

I'd assumed all along that the optional console was merely a "plug in from top'" type design, but then the introduction of the two different styles of the "5 switch" accessory caught my eye. Confusingly, they visually seem like they should be "interchanged" for a long console that is meant to provide a connection tunnel for HVAC....
