Hydraulic pipe in trunk : Which one

I've started to add the option 881, which is the automatic trunk close, on a 2012 R231 SL500

It use two hydraulic cylinder (one on both side), which are used to open or close the trunk. Each cylinder has 2 pipes which are connected to the hydraulic pump.
There is, on each pipe, a number printed in white, in order to be able to connect the right pipe at the right position.
Unfortunately, the same number is not written in the cylinder : i dont know where to connect the pipe.

On left pipes, one has 71, the second one has 81
On right pipes, one has 75, the second one has 85.

Can you check on your car which one is connected on the lower part of the left cylinder, and same for the righ cylinder ? It will help me a lot.

I will add picture to be more clear.

Michel
