Wiring Diagram for Rear Wing

It would take a massive amount of work to complete and most likely offer 0 in terms of braking performance.
I am not trying to be negative, but its a lot of work and due to the Scooby bodyshape, it would need a huge spoiler to have a positive effect.

Your statement is a bit weird...

When you have an 800bhp car, what you need is massive brakes, a solid suspension and a perfectly designed/angled wing (rather than specifying massive or not...).

Since I have experienced the usefulness of my current wing, I am 2000% sure that using it as an air brake (linked to the braking pedal) will be perfect for my application...

Good luck old chap. IMO I think you are missing my point as I am referring to the Porsche spoiler, not a huge aftermarket contraption!
The std wing is aerodynamically designed for the Porsche Boxster shape so would not necessarily have the same performance on a Impreza shape body.
My many years in the aerospace industry have taught me this at least.

If you have bigger plans, crack on son......

I am using the mechanism alone, without the Boxster spoiler.

this is unbelievable.
i took the spoiler apart, and found out that the extra wires going to the motor, are actually going to a switch, that seats on the rail.
there goes my "knock sensor" theory.
the switch basically detects the movement of the mechanistic, and send command to the clusters . very old school in my opinion.
could be the switch in my spoiler is defected, that's why it works only manually.
this is the switch (yellow arrow):


having a look at the way the mechanistic is build, i don't think there is a way to make it work faster. the motor spins a gear that spins a spiral cable, so you are loosing speed, but the motor gets the required torque to push and pull the spoiler.

oooops...
the pic with the arrow:

I was wondering about that too....

Does this switch sends the commands to the clusters or the opposite?

I say the clusters do to that switch since they detect the speed of the car and send the order to the mechanism to either expand or retract.

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.
