912is Included Items

I've purchased a 912is engine from a Kit plane company who is parting a plane out for a customer who will not complete it for medical reasons. Once I decided I wanted to purchase the engine they removed the engine and components from the plane for crating to be prepared for shipping. The engine is supposed to include the items that came with it from Rotax as it was new when installed but never completed. There is a bit of confusion on which components came with the engine and just the identification of some of the components. I'm trying to get some info on what comes with the engines typically and maybe some pictures or an inventory list so I have a reference to do an inventory when it arrives so if anything is missing they know what to look for as they've assured me they will send anything they've missed. Is the wire harness more than one piece? I only ask this so I can make sure there aren't any smaller sub harnesses or couplers/plugs that could be missed. Are there any components other than the engine, oil tank, ring mount, fuel pumps, wire harness, fuse box, ECU, starter/relay, radiator/expansion tank, exhaust system and manual/paperwork? I know they don't typically work with Rotax and may not have installed the engine so they aren't completely familiar with it. Thanks for any and all help
