I cannot get this to work; at first, I could not get the Legacy parts to work, no matter where I put them. Just tried reinstalling everything, and now don't even have the IR tab in game. I installed before using CKAN, did it manually this time. I have all the latest files, KSP 1.1.2. I have a MagicSmokeIndustry folder with Parts, plugins, assetbundles, plugins folders inside. I had to move things manually (the GameData from the Resources folder), as unzipping into the KSP folder did not just merge the GameData like usual; am I missing something? There are a lot of other folders and files not under GameData, where do they go? I'm feeling rather stupid right now.
EDIT: Through CKAN, I uninstalled both MagicSmoke and the Legacy parts, then reinstalled them. I now have the IR tab in the game, but still no Legacy parts.
