i'm in the process of relocating my tfi module in my '88 bronco II. first of all, how hard is it to take the distributer off and is there anything i need to know other than just unbolt it an bolt it back up? another thing is i noticed in the write up that you have to make a block off plate for where the old module used to be, but i took the old one off and all i can feel is a blank surface, no hole other than where it plugs into.
