Mine is a 94. when I say "made" i mean replace the wire(s) because they get brittle. people hear say replace them if you tear down the top end cause your there, but they are $150 OEM or after market. the only goofy thing is two wires come off the high side and only one is connected and the sensor. It appears the second wire is wrapped up "looks factory". hear I'll post a pic or 2. I was just trying figure out what was inside before i just tear into it.
