Still working on this (the driver adjustable TOD) -it's not as easy as you're making it out to be. I could build the circuit for myself and make it work, but it would be difficult for others to reproduce.

The DCCD in the Subaru STI and the "Grid Dancer" ATTESSA controller available for the Nissan Skyline have exactly NOTHING in common with the Borg-Warner TOD except for purpose.
Neither of those cars use a transfer case -they both have center differentials.

The manual transmission can be done in a TOD VX, it has been done by rally teams. Rather than re-invent the wheel, we need to get an undercar shot of a rally VX -so we can see if a custom adapter was made to match the tranny and transfer case together. I'm not even sure what kind of transmission it is -it could be a commonly available Getrag unit from the aftermarket -you can't tell just by looking at the stick. I had assumed that it was an MUA-5, but this seems to be unlikely.

Someone find an undercar shot of a 5-speed 'rally' VehiCROSS and we'll have our answer.
