Hi did a search but didn't find any info. I'm needing the pcm pinouts for an 04 silverado. I think that all the pcm's from 01-up are the same?? correct or no? Anyway if anyone can help me out with a pdf file or link I would appreciate it. I'm shipping my PCM off to Allen next week to get flashed. I want to get started digging through the harness and doing some cleaning up and labling. Thanks!!
