I've done a few similar swaps, and found there are really two options, 1. Keep all the factory equipment on the engine, or 2. get with one of the companies who modify and or build new harnesses for the 5.0's and use their products and advice. I had a link for the guy's harness I've used before, it was a modified OEM harness. Unfortunately when my old computer locked up the information stayed there..... If you can't find the information you need, let me know and I'll do some research and try to find it again, might have the invoice around yet, not sure.... At one time, I might have forwarded it to a couple of the Ford guys here, maybe one of them still has it?????

Love them old panels!!!!!! How about some in-progress pics as you go so the rest of us can all be jealous??????
