I'm wondering if you guys can help me identify the year/make/model of my PCM (if it's possible?).

The number on the PCM is 16238212.

Is there anyway to validate this came from a '98 LS1 M6 equipped car? Does it matter if this PCM was originally auto or M6?

Also, how do I identify if my engine harness is for a '98? The only thing I can see on it is the section that comes into the cabin. It's got a bar code and a sticker with #207561 and it has 3 plugs.

The other harnesses I have seen pictures of, the interior cabin section only has 2 plugs.

Any help will be appreciated!!!

Yes, its a 98.

The hardware is the same for manual or auto, however it can easily be reflashed for either if it's the wrong version for your application.

Okay, awesome. Thanks for the reply guys.

Any info or advice on identifying what year my engine harness is?

This might sound a little crazy, but I believe the 1998 harness uses a 3 pin connector for the coolant temp sensor, and 99-02 uses a 2 pin.
