I just bought a 1998 S70 GLT. My 3rd Volvo as of yet, but my first S70, anyone with experience in these I could use some help. It's not a big deal I was just wondering where the best place to break through the fire wall would be? If anyone has an idea let me know, I wanna check and see befor I drill my own, thanks for your help!

There should be one on the drivers side. That is where my Boost gauge piping is going through,
