Default PCM pin numbering

I have found some missing wires and some cut wires in the harness I bought. I'm not totally sure what year it's from, I just know it's not a 98.

The alternator now only has the one red wire. I have read this is bad and would like to fix it.

I have no idea how the numbering sequence goes at the blue and red connector. I thought they were shown in the FAQ here, but the images are broken. How does it go?

The red and blue connector are numbered right on the connector. Look just above the wires, its kinda behind the grey plastic cover.

If it is an f-body harness there should only be a single red wire going to that alternator plug.
