To locate it more precisely:
* Follow the shift linkage: Trace the linkage from the shifter inside the car to where it connects to the transmission. The neutral safety switch is usually very close to this connection point.
* Look for wiring: The switch will have wires connected to it, typically two, going to the ignition system. Following these wires might also lead you to the switch.
* Consult a repair manual: A repair manual specific to your 1988 Reliant's make and model (it may be a Plymouth, Dodge, or other Chrysler brand) will have a diagram showing the switch's location.
Remember to disconnect the negative battery terminal before working around any electrical components.
