What is the PCM? Does it have blue and green connections? If yes, it is a one megabyte P59 PCM and this will limit you a little on what you can and can't easily do with that PCM. There is only one P59 PCM operating system with good XDF file support for editing - OS 12587603.

What is the PCM Hardware Number on the label?

What do you wish to do with this PCM? What transmission will it need to support?

Have you read any of the discussions around here or on You Tube about "LS Droid", "PCM Hammer", "Tuner Pro RT" or the construction of a bench wiring harness for your LS PCM?
