i just got done doing my alternator and now i have a sensor of some sort that i don't know where it goes. it's connected to the same finger of the sensor harness that plugs into the spark plug box, and it says "PBT-GF30" on it. it's got a metal clip on it that looks like you just screw it onto something, maybe for some sort of ground? i don't know where this thing goes and i don't want to start my car without attaching it.. i lost my camera, otherwise i'd take a picture of it. if anyone knows what i'm talking about please let me know ASAP as this car has to be ready for racing tomorrow!

i also did a search on google for "PBT-GF30" and it came up with the mass airflow sensor, but it can't be that since it's on the other side of the engine bay, and it doesn't plug into anything...
