I have been trying to find the hood pin wire in my 93 for over an hour, and can't. One of the wire code diagrams I printed off says it's gray/black, but I can't find any that are that color. I've used a voltmeter on almost all of the wires and I still can't find it. I know it exists because when the factory alarm is armed, and I pop the hood, it will go off.
