Hi guys, I know there are lots of threads on this. But I am having a hard trouble finding a place to get through the firewall on my JDM Evo 7 (RHD). I am doing a boost gauge install and I cannot seem to find a good spot to get through with my screwdriver.

This is the passenger (left hand) side under neath the glovebox area.

Hear is inside the engine bay not sure if either of these places would be a good place to go.
