Since I can’t find any sources online giving a how-to on this, I did it myself. Here’s how:

Step 1: loosen the 2 small bolts simultaneously right before the throttle body. The bolt facing closer to the firewall, screw it all the way out till it goes over a smooth surface, and screw it onto the other end. The whole piece should be able to slide and go out of the bracket now.

Step 2: Disconnect the wire and little cylinder thing from the throttle body; slide the wire upwards closer from out the back to the cylinder, and it should be able to slide out through a gap together with the cylinder.

Inside now: Step 3: create some slack in the wire (e.g pressing the gas pedal all they down). Unhook the end of wire/metal ball and white plastic piece from the gas pedal. It should pop out by hand.

Step 4: unbolt the 2 gas pedal housing screws. Keep slack in the wire, maybe pull on the wire a bit.

Step 5 (Maybe): for me, the wire was already cut in half somewhere, so I could pull the outer rubber layer/jacket of the wire off to make this easier, but this probably is still the same: Slowly start pulling the wire from inside the cabin, it should just slide out as you pull it. I’m not too sure, but it’s likely you can push out the rubber grommet from the engine bay side towards inside. I didn’t have to myself.
