For a TCS, both the heater valve cable (more like a stiff 1 strand wire) and the choke cable go straight from the front of the centre armrest into the black hole and through the chassis near to the hand brake cable and the radiator flow and return pipes.
For a RHD TCS car, the accelerator cable goes from high up by the right foot of the passenger,diagonally along the left side of the centre chassis tunnel, and out through a hole where the firewall meets the floor to the right rear of the passenger seat.
For a RHD TCS, the clutch cable is held by a bracket where the tunnel meets the floor about under where your left knee (driver) would touch the floor if your left leg were double jointed. It then goes along the bottom by the left side of the seat and out of a similar mirror image hole that the accelerator cable exits on the other side of the tunnel, where the firewall meets the floor behind the driver's seat.
The clutch cable has two different types of brackets to hold the outer cable by the bottom of the engine. It can either be welded to the left Y leg of the chassis, or it can be a bracket held with 2 x 1/2" head or 5/16 UNC bolts to the block.
