I don't see why you couldn't get away with unplugging it and shorting the wires. I'm assuming that's all its looking for is a short or low impedance on the line. What sensor are you talking about? I knew the GEN 1's had a light under the hood but I didn't realize there was a sensor involved with it. If you're just worried about the light coming on, just take the light out. Is there a message indicator saying the hood is open?

The hood switch has nothing to do with the engine compartment lamp.
The hood switch is for the anti-theft function only.
The engine compartment lamp has two switches - both integrated into the lamp assembly itself. One switch is a mercury tilt switch and the other is a manual override slide switch. You may use the manual slide switch to turn off the lamp when the hood is up for extended periods. Of course the tilt switch turns the lamp on when the hood is up and turns the lamp off when the hood is down.
The hood switch is a spring loaded momentary normally closed switch to ground if I remember correctly. If the hood is opened with the alarm armed, the switch puts a ground signal to the anti-theft module and the alarm will go off. If this is correct, you can just unplug the harness at the switch. If I am wrong, you will need to short across the unplugged harness.
Bottom line - you can disable the malfunctioning switch until you get a replacement. Of course, without the switch the hood being jacked open during a theft will not set off the alarm.

Well, if its a closed system, you would just connect the wires....... if its open, then leave them unconnected -

I will try to look at the EVTM tonite and verify whether or not it is normally open or normally closed.

The EVTM shows the hood switch as a normally closed switch which grounds pin 5 of the anti-theft controller module. The anti-theft hood switch is closed with the hood open.
From the manual:
An Anti-theft Hood Switch is also part of the system. If the hood is forced open while the system is armed, the switch closes and a ground signal is applied to the module through the 26 (W/P) wire. This triggers the system in the same manner as the Anti-theft Trunk Lid Switch.
To disable the switch, just unplug the connecting harness.
which switch is it driller? the one on the left side?
