Making a engine harness. What to use for alternator

Hey guys I am making a harness for my engine. Mostly I am eliminating all the un used wires and using all new wire with clipped off sensor pigtails.
Anywho I only have one thing I'm not sure of. What do I need to use for the alt wires. I have done some research and see I need a 3 volt key on reference and a 12volt constant...????
What can I use for these off of the factory ecu and are these values correct?

Did you look at the factory wiring diagrams?

Yes. But I couldn't find the info I needed. The oem charging plugs were not in the harness when I got it and the diagrams dont really say what amount of voltage goes to what pin when the key it's on/off/run.

Ok well what other wire can be used for the 1v key on/ 12v idle I cannot find this white/black wire in the engine harness.
What I'm asking I guess is where is the other end of these wires so I can test them.
