I did order a set as well. In fact both modules, the window control and mirror folder as well as the roof window closer.
First I tried to install the roof window closing module but failed because they have sent me the wrong harness. In fact the module is plugged directly at the drive motor plug. It's a bit hard to get in there. You need first to remove the map lights module with the controls. In fact I did a how-to in
this thread even though it's related to microphone issues. You might wat to check both in one step too.
After removing the map lights compartment you can see the roof window motor right underneath (or on top actually). The motor for my EUDM MY2016 Levorg is branded webasto and got it's connector on the left (driver side, LHD model). To disconnect the cable you can stick in with a flathead screwdriver and push out the connector. To ease things you might lower the ceiling a bit by removing the "gasket" around the roof window (yes, just pull it off).
However in my case they have shipped the wrong cabling. I actually ordered the one for Subaru XV 2018
here but asked them to check the harness. In fact my motor connector looks exactly like the one on the product picture. Even the dark gray color is the same. Unfortunately they sent me a module which has a "Levorg" sticker on it but the harness seems to be from the Forester/Outback model. It looks like this harness
here. So it does not fit. I have asked the seller to send me the XV/2018 cable instead.
There is actually a second connector and Subaru just sticked in some sort of "adapter cable" from this connector to the roof window motor. But neither of those connectors are compatible with what I got. According to the mounting instructions they prefer to interface directly with the drive motor connector.
Another side-note... The module seems to offer auto-closing after 3 seconds when you turn off the engine. But it's instructions also list a mode where you can get the roof closed when you lock the car. Unfortunately there seems to be no "lock" signal up there on the roof harness. So you would have to run the signal wire all the way from the door via A-Pillar to the roof window module. Not a huge deal but I am not sure yet if I would like to get this installed.
The window roll-up/down module was simple to install. It's just plug-and-play and I see low risk of installing it. In worst case your driver door might not unlock if something is wrong with the cable or bad wiring/module might occur in the future. As well as of course failing to roll your windows up/down.
To install it you of course need to remove the driver-side door cover which is simple to do:
- Remove the Philips screw underneath the plastic cover inside the door opening handle molding
- Remove the Philips screw underneath the plastic cover inside the door hande molding
- Pull off the cover from the bottom or use some pry tool - yes they sit pretty firmly and you might break some of them
- After releasing the clips lift the dor handle up to release it from the upper side (it's just hung in from the top/window side
Be careful not to pull off the cover too much in order not do damage any wires or the door unlock cables. Carefully lift it at the bottom and then pull the whole thing up slightly and put it on some support stand or ask a friend to hold it up while you're disconnecting everything if you need to. I found it actually easier to unscrew the door lock handle entirely from the door cover rather than to release the cables from the handle. But to install this module I didn't even release anything, just gently pulled the door and disconnected the wires and installed the adapters.
It's a surprising large amount of cabling you have to snap into but the harness provides Y-style connectors for all of them. So you can't do anything wrong as all the connectors are different. You need to plug in the harness to the doorlock actuator, the window control connectors as well as to the mirror folder/control unit. On the other side the harness has a quite beefy connector which goes into the module itself. The module actually isn't much more than a bunch of relays in a box. You need to find a suitable place inside the door cover to mount it. I trashed the included double-sided tape in favor of some super-sticky velcro as it was not sticky enough and I was basically unable to find a large flat surface. The best place I figured out was on the bottom side of the door cover but you can put it everywhere. The harness also includes a 30A fuse. Keep this in mind in case your power windows do not work any more, it might be a blown fuse not only in your fuse box but inside your door!
The module works as expected, all functions I tried work fine, including automatically closing all windows when locking the car (along with folding the mirrors) or rolling down the windows all together on keypress. You can also interrupt the rollup/down process to keep the windows half-way open. The lock-unlock-lock function might be handy sometimes as well, it's leaving the windows open just about 1-2cm so you have some airflow.
If you got dogs or even your kids waiting in the car for a short time you might use unlock-unlock-lock combination to lock the car intentionally without closing the windows.
I personally like that my Levorg now assures that my mirrors are folded and all windows are closed when I lock it.
What I don't like too much is that those modules are not configurable at all. For example I cannot simply activate/deactivate the mirror folding function by programming it or even more simple by setting a jumper on the module.
