when putting in a new AOD in my bronco I had to hard wire the N/S switch since the shift rod inside the new trans was the wrong one.
I took the aod harness and just took a 2inch lengh of wire and my haynes man. and looked at the diagram. I found the hot wire that powers the switch, and them had to find the starter one. One would enguage the starter and not shut if off and one would allow you to start and the starter would shut off (like normal). I jumped to the one that allowed the starter to shut off. These two were next to one another in the harness. I spliced the wire to gether and now the truck starts in any gear so watch out, but works fine.
