Huffer

I'm repinning my 1227727 and have found a possible problem. I'm using the pinnout mapping I got from the gm-ecm site and found my connectors are Orange (A), White (B), Green (C), and Blue (D). There are some color differences in wires.
I'm replacing a 165 and have the pinouts for it as well. Do you think it is safe to assume the functions (pin out) are the same on this 727as the one being shown at the gm-ecm site? Do you guys think it will be safe to just match the functions between the two computers and disregard the colors?
I need to have this bad boy running by tommorrow afternoon.
