Default Need ECU Pinouts? Then look inside.

I've been looking at this for a while. Too many people need to know what goes where and the information is hard to dig up.
-If you have a generation that is not listed here please add it to the post and I will copy and add it. (Keep them all up top)

Nice!

I assume you no longer need my help? I had been trying to round up all the pinouts, but I just didn't have time to sit down with the manual.
