It would be great if someone had it in e-form.

My confusion on the tach and speedo stems from reading that the old computer controls the speedo, and I assumed that both pcms needed the signal.

I have some materials coming from S&P, and hopefully they will line me out a little more. I am positive that everything will start to make more sense if I just pull the truck into my shop and get started.

I think I'm making a bigger deal out of it than it will turn out to be, but I'd rather be overprepared than get into it and find out I should have asked more questions. I never found a ~great~ writeup on this, so once I figure it all out I will try to put it all together in a way that really explains what you are trying to accomplish as far as which computer will control what etc.
