IASF Prongs

HI again,
I'm wondering if there is any way that I can figure out which prong is which on a 4 prong regulator. I'm asking because I'm working on my 69 E150 and the wiring has been butchered. I can't tell by the colors of the wires because I have to run new wires anyway. Many don't exist. I bought the connector from OReilly's but the IASF aren't on it. I think the regulator is mounted in the way that it was from the factory - so could I trust the top prong to be the I?
Thanks,
Scott
