Oil lines and electrical question

[j930]

Since buying my 930 I have been cleaning and tightening etc etc. I had a small oil leak out of one of the oil lines on the passanger side rear. THis is the metal line that sweeps around the back of the car and then becomes another line that starts off as a hose then turns into metal and terminates just behind the driver door. The previous owner decided to just replace the hose instead of the whole line and it is leaking. well now I see why.. Getting the end off at the back of the car is simple but the line that terminated just behind the passenger door....... I have no idea how to loosen the line from the "oil hub" that it goes into. THe space is very tight and there is no way of getting a wrench up there. ANd the wrench is rather large i think a 36MM. it appears to me I would need to somehow drop the whole assembly down but all of the oil lines going into this hub are metal and that in itself seems a bit much. Am i missing something?

Secondly I posted a picture of a wire last week that appears to have nothing to go to. It is a set of wires that is defintely factory and comes out of a wire bundle that exits the rear of the engine compartment and dies at where the starter is. The heavy wires that go to the starter are in and connected and these smaller wires( 1 brown and 1 that is yellow with a green chaser or vice verse) seem to have no where to go. I see nothing else any where near there to connect them to and I believe everything is working. ANy thoughts on this

my apologies in the second line I meant to say passenger door.

This may help with the oil line replacement.

The wires look like they might be for the back-up switch at the front of the trans. above the trans. mount.
