the relays are activated by the cluster.
so the switch "tells" the cluster what is the position of the spoiler, and the cluster will activate the relevant switch based on that.
i guess that the switch also let the cluster know if the spoiler is fully extract/retract, so the cluster will be able to stop triggering the relay.
next step for me, i will connect two indicator lights to the cluster wires (see diagram), and will drive the car. i would like to see if the cluster send command to the relays.
if not, i will override the switch and test again.
in your case, you can connect directly to the motor using 2 after market window roll up modules. as i suggested before.
when your switch is spreed, it will activate one of the modules, and will extract the spoiler. when the switch is released, it will activate the other one, and will retract the spoiler. you will need a switch with both NO and NC contacts.

More info that might help.

The two gray wires on the switch will close circuite when spoiler is fully extracted, and the two browns when retracted.

Thank you Meir, that is excellent info.

Something came up in real life, will put this project on hold until coming Friday.
Will update y'all until then.

Ok, got to the bottom of it.... Pics says it all ;)
