You're really asking for trouble. Either stick the right one in or trade the car for what you want. You'll be missing sensors and solenoids so the Check Engine light will always be on. The Engine Computer will be different. You'll have to replace the brake pedal assembly and add the clutch pedal. The starter wiring will need to be changed since you won't have a neutral safety switch. You'll need a clutch switch instead. If you wire it direct so a clutch switch isn't needed, insurance investigators and lawyers love to find any kind of modification like that.
To see what other problems you'll be in for, visit the dealer's parts department and ask to see how many parts are listed as "with automatic" and "with manual". Engine cross members can be different. Coil springs need to be stiffer for the added weight of an automatic. And those are just the things I can think of quickly. I've seen people try to do these types of modifications and they rarely turn out successful. There comes a time when someone has to change your mind to avoid lots of cost, time, and frustration. Honda doesn't have much transmission trouble so if you're just trying to find the cheapest alternative, find an automatic from the same year and model in a salvage yard.
