Deciphering PCM labels

My '99 1LE came out of Cali 8 years ago, the engine was not original and was listed as an LS6. Since it didn't have the original engine in it, I'm trying to find the origin of the PCM. Can anyone decipher these numbers ?

What part is this ?

When I brought the 1LE home, we had it loaded with parts. I just gutted the interior to remove the rollbar, and found a component that I'm not sure what it is or where it goes. It has "sensor" molded into the plastic, and a tag on it that says "Theft deterent shock sensor". I'm just not sure if it is off the car or a spare, any help appreciated !

Kooks LS1 stepped headers, PCM and Harness, Momo wheel and quick relea

Kooks LS1 1 3/4" - 1 7/8" stepped headers, with 3" collectors.
- They came on the 1LE when I purchased it. At some point the AIR fitting on the passenger side came off during an AutoX event, and the header was patched (can see in pics). Since the system was fully welded, the 3" aluminized Y-pipe was cut to remove it, you will see the pieces attached to the collectors. I will remove these pieces before shipping OR I can leave them on and give you the Y-pipe for free, if you want to pay the additional shipping cost. Bolts and O2 extensions included.
