^ this would work out best. Not only do the plugs not work, but if the ecu is in stock location it's a bit of a pain to reconfigure. Standalone with a/c is fine if done correctly. Take it back to the people who did your sedan, they should be able to figure it out. There's nothing different about your swap at all, its been done many many times and all the info is here if you take the time to research.
