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...

is it this sensor?

yep i got it, it's the radio noise supressor right? that's where i plugged it back in, thanks for the help though!
