Change ES to Foot Shift

I am wondering if somebody can explain to me in a very detailed manner on how to convert my 2001 Rancher 350FE ES to a foot shift. I understand a little bit as far as removing the shift motor and getting in and removing the reduction gears but I am not the greatest mechanic, just self taught/made at it.
So if somebody’s possibly got some pictures or very good at explaining how this all works that would be a great help to me. I already have my bolt on foot shifter also. Just need to disable the ES.
