The electricity only goes to the pump in the trunk.
The first picture shows the air/vacuum lines (yellow) leaving the pump area going to the doors, hatch and gas cap door.
The second picture shows the line going to the lock in the door, passenger door shown but the other is the same.
the central lock works through the K54 relay I believe
side track....I thought the XF didnt use this, well, traditional MB vacuum method. I stand corrected.
interesting to see a couple differences from a slk32. looks odd NOT to see the hydraulics for the roof in the left pic. uses same vacuum tubing but the trunk line is routed different and the tee is different. I am changing out a slow leak vacuum line from the the PSE (in MB terms) to the passenger door. Actual leak is after the tee to the trunk and before the passenger footwell. Have to remove carpet panel behind seat and hopefully leave the seat in place, fishing the line through the tunnel.
