Generally... Japanese cars have a neutral start (inhibitor switch, to them) mounted with two bolts to the transmission, behind where the shifter cable/arm attach to the transmission. Place the tranny in neutral. It's easier to remove the arm (use channelocks if nescessary to hold the arm) and remove the nut, then the shift arm. Look at the switch, there should be a small notch in the plastic portion of the switch that will align with a slot in the portion that keys to the shifter shaft. Loosen the two attaching bolts and rotate the switch until the notch/slots align, then retighten the two screws. Reattach the arm and cable and you should be good to go.
Then again, the SVX might be totally different and none of this will apply.
