Im_No_Pro (neither am I) - Hi and congratulation on your new purchase. I assume that you are referring to my fix. If I'm correct and whilst I hate being the harbinger of bad news - I'm not sure if you will have the degrees of freedom with the blank switch positions that is inferred in your post.
Here's a copy of my understanding of how the switch-set is connected in the RHS fitting of the center console (I believe that the LHS switch is similarly arranged)
Notice that except for the "Tire-set" button, each of the other switches have one end of their contacts connected together and connected to the car's earth. The reason that I selected the "Tire-set" switch for my solution was that it was the only switch with contacts that were independent of the other switch contacts and also independent of car's other wiring.
The problem with my suggested solution if you use any of the other switches is that you are interposing the car's earth point into the ciruit for the remote garage activation fob. I guess that you could be lucky for this not to be a problem if you use the fob battery, but it's a risk that can only be mitigated with a copy of a ciruit diagram of the remote garage control device (not usually available). Most definitely don't do this without a wiring diagram of the garage opener if you elect to replace the battery in the remote garage device with a power supply that is related in any way to the car's battery.
The other solution that you could try is to cut the copper track on the printed ciruit board for the switch bank (2nd last item in the picture below) that earths one end of the switch. This then isolates the switch, but you will need to find a vacant pin to connect to the now isolated switch contact

Please don't PM to ask questions about coding, or vehicle repairs. The better place to deal with these matters is on-line, in the forum proper. That way you get the benefit of the expertise of the wider forum! Thank you.
