The CAS pin on the flywheel questions...where is this?

I removed my access plate from underneith and see my flywheel, one sensor looks to for some reason read the teeth? The other is on the opposite side of the flywheel of what's visable. Soooo, how do i check if this pin is in place? Alsooooo, i found chunks of metal in the access plate, they're semi circles, noooo clue why that'd be in there.

I'll get something tomorrow, i was working on it last night in the rain and it's still raining, i don't care to roll around in the rain gathering those pieces from under the car again (i can't move it currently).
