The neutral safety switch is on the driver side of the tranny,get under the car and look for a rectangular grey box,it will have the linkage rod attached to the center of it,its bbest to have the car somehwat lifted to have better access to this,youll need a 10mm socket and a wrench or 2 wrenches to loosen the 2 bolts on a clamp that holds the rod to the switch,anyway it would also help to inspect the pins and wires arent broken off(they connnect to the side of the nss) have a good look forst before you remove,good luck.
