2000 C5 PCM Diagram
Hello guys, I'm new to the forum, and would like to ask a few questions to kick things off.
1.
I'm looking for a PCM Pinout Diagram for a 2000 Corvette with manual transmission.
I've used the SEARCH function and have found some results but all the links posted were invalid.
If you could post the diagram(s) here or send it to me at zzquad@netnitco.net I would be VERY greatful.
2.
In a related question, I am looking for a tach signal at the PCM on this same car.
I believe that this is pin #10 (not pin #35) which is in 4-cylinder mode.
Can anyone verify this for me?
Once again, thank you!

There's something going on at LS1.com where the diagrams used to be. They keep moving them around. I'm trying to find them for my own use. I'll let you know if I find it.
