While I changing the oil in the XJR I noticed some fluid coming off of what I assume is the AC lines. So I am guessing that must be compressor oil? My vehicle still has its rear end off and is on a lift so I can't see from the top yet. But does anyone know where these lines connect to? I can't really find a diagram that shows the other end of these lines.

With that said, anyone replace these? Something tells me it is not easy to get to. For reference these are from the underside of the vehicle on the drivers side. The lines are behind the engine and loop to the other side or I assume go into the cabin?
