which PCM to use for an OBD2 conversion

My 95 was OBD1 and I've already pulled the harness and PCM out. I've got a 98 5.7 w/4L80E truck harness I'm using to retrofit to use with an LS style PCM and using the efi connection 24x kit. I've seen tons of threads that mention the 0411 PCM and thats fine but would a 99-02 truck PCM not work as well? I will be running it on a 2002 6.0/4L80E based tune. I just need to know what PCM to be looking for.

The 99-02s are of the 0411 type

99-00 used the 09354896
00-01 used the 12200411 this is referred to as the 411 PCM

They are both 512K PCM's and you can flash the later 01-02 OS on to the 99-00

To answer your question, Either of the 2 listed PCM's will work.
