Auto to manual conversion

Alright i am going to convert an auto d15b civic to a b16a2 manual. I know how to do a manual to manual but not an auto to manual; conversion.
Im just wondering since its auto to manual, what needs to be done? Would i have to touch the loom? And i heard i may have to drill onto the shifter hole? And what about the mounts or is it straight bolt on?
