I am looking to swap PCM's, and was wondering if the pin-outs are the same. I want to put a 2004 PCM, # 12586242, into a 2003 that has #09354896. I will disable VATS. The 2004 is supposed to have a faster clock and more ram, if I am reading correctly. I was wondering if the connectors are the same with the wiring all being the same at the pins.
