The video helps. The air duct is just a temporary diversion as you mention. Your wur is mounted opposite of others as the vacuum line typically points away from the engine. Not a problem, just looked different without the line visible. You have an interesting mix of components that is well above my head to sort out. It looks like you have both vacuum assisted components and a lambda trying to control fuel mixture. Usually the two don’t play well together. I would wait for Tony to chime in....
