Bulkhead access to drivers side.

I am looking to run a boost gauge tubing to the drivers side vent.
I spent a few hours yesterday trying to find a way, but have not found one, took the battery out to see
if there were any bungs hidden, but the only ones are between the battery and the pollen filter
but I guess these come out behind the glove box.
I would prefer it to enter on the drivers side, I no you can go though the ECU box, but I don't want to remove wiper to access the screw behind.
I have read various guides online, but these are for LHD cars so it seems easier to get to the drivers side.

What no one has the answer?

Guess you never found a way, I could find one either,
Looking at the ECU cover, I can see the torx under the wiper and cover, I could nearly reach it with the small Bosch tool set,
but just out of reach, if it was just a bit longer I could get to it, annoying really, cant do it with my 1/4 drive ratchet or flexible shaft.
