When we did the conversion we had the gearbox and engine placed in the car.
I can not find anywhere on the gearbox to place the cable so my guess it is all electronic from the gearbox. There may be somewhere to place it. I do not know the model of the gearbox but it was out of a JZX-90 Chaser. ( auto Gearbox )
We can put the dash from the chaser in there but it is going to look tacky.
