I am looking at the Electrical Troubleshooting Manual and according to the diagram there is only one wire going to that switch (wich is strange 'cause I remember seeing three contacts on the switch), the brown/red wire. The brown/white is not used. ("Taped to harness for hood switch. Switched ground when alarm system is armed."). You can try putting the wire on one of the contacts (raise the hood, depress the switch, lock the driver's door with the key and let the switch go) and see if the alarm comes on. Just a hint. Good luck.
