i just recently found a plug that was unplugged on my car. its right below the wire harness that plugs into the front o2 sensor not the one right below it but its vertical. its plugging into a silver box that says high voltage its about the half the size of a deck of cards. the plug plugs in from the bottom and this is on the left side of the car
im putting a pic with it but its from my cell phone so bad quality
just thought id try to figure what it was to i have been looking all over ken gilberts pages but cannot find it. maybe the the ABS system... ???
