1978 ignition switch wiring diagram

1978 E-250, 460, Auto, AC
I have electrical diagrams but none of them show the electrical connections to the actual switch connector. I took a picture before I pulled the wires but I didn't check the exposure. My Canon digital Rebel no longer sets the aperture in the auto modes.

Anyway, if someone can list wire colors and pin designations or provide a diagram, I will be back on the road.

At a minimum, if someone could tell me what the designations stand for I could probably figure it out based on the other diagrams. Otherwise, I'll hook up the bat and test them when I get home. I just don't really want to be guessing here.

I (1 and 2) = ? guess ignition
P (1 and 2) = ? guess power - "key on" not accessory
A (1 and 2) = accessory
Bat = Battery

Thanks for any info!
