Editing modules into a save file?

[SpacedInvader]

So after reading that the ISS primarily uses flywheels to keep its attitude stable, I've decided I'd like to add reaction control wheel modules to the station I'm currently building in orbit. For future components, I don't think this will be an issue as I'll just make a MM config adding in the wheels, but for the parts that are already in orbit, my understanding is that they will not include the new modules because of the way they are saved. Is there a way that I could edit the reaction control module into the save file without having to relaunch all of the parts I've already go in space?

Nevermind, I guess after a little experimentation that editing the parts with the new module actually does translate into the new module being on the craft already in space. I'm not asking for this thread to be deleted so if anyone else has the same question they can find the answer more easily than I did.

Yes. The easiest way to figure out what you need to copy/paste would be to make a simple craft with your part on it and launch it. Quicksave, edit the file, and look for your newly launched ship. You should be able to spot the new section of code that you need to copy and paste into the corresponding part on the station. Just make sure you don't try to copy the whole part. Just the module you're adding, or it might unlink your whole station.

Keep a backup copy...

Good luck,
