2012 Electrical Diagrams

What is the difference between the 12v electrical diagram and the 24v diagram?

The difference lies in the use of 24 volt pneumatic valves and the associated wiring to the Crio solenoid module.

To elaborate: If you are NOT using any Pneumatic Solenoid Valves that operate on 24 Volts, use the 12 V diagram. Otherwise, the 24 V diagram shows you how to supply those valves with 24 V legally. Note that they do make solenoid valves that operate on 12 V.

And for our readers where specifically are these diagrams? I have looked on the FIRST site and could not find them.
