Installation is the reverse of removal: just push things back in place and they will snap back. There won’t be much slack at all and, if you need to do anything to the port itself, you’ll want to pop it loose (one clip on each side to the left of my thumb in the picture). The result will be the shroud and OBD port sitting just free of the dash. The solution is quite simple: get a non-marring stuff pry bar and carefully lever out the shroud from the driver side while pushing from behind the dash. If we had more room behind the dash, I’d recommend sliding a thin shim or pry bar down the side of the shroud but it’s quite cramped back there. The clips are quite a ways down and, since the OBD port will be in the way, there’s basically no squeezing that you can do that will get things loose. What you can see in that picture is the shroud out of the dash (so I did figure that it out, obviously) and my thumb showing about all of your potential squeezing area (i.e., not much). What many of the posts online recommend that you do is a variant of “reach behind the dash and squeeze super hard and magic or something.” What you’ll see in the next picture is why that strategy falls down: Looking at the upper left, you can clear see what looks like the back side of a clip that fits the shroud into the rest of the dash (and you’d be right to think so). That shroud is what we are trying to get loose. vauxhall corsa b diagnostic obd2 port location video - youtube.

In that picture, you can see the OBD port (the connector with many little holes) and the shroud that it sits in. Vauxhall Corsa Fuse Box Manual B130 Wiring Diagram Computing. Here is a picture of the area that we are taking about (this is the view from your lower shin when driving the car, if you have eyes down there): This is actually easy to do and yet all the online posts seem to be completely wrong (at least relative to my car). Tl dr: gently pry it loose from the driver side and push it out from behind the dash
