Boost Gauge: Where to drill through firewall?
Been reading about installing a boost gauge but would like to know where exactly would I drill through the firewall. Read the easist location was at the steering wheel, but where? Posted a picture so you guys can help or if another location would be easier.

You don't need to drill. It's a tough passage but you can go through the big hole by the brake booster, inside the fender, and come in next to the fuse box. Could probably remove the fender liner to make it easier but I try to avoid drilling holes in my firewall if possible.

Some people drill through the rubber grommet near the steering wheel but that's kinda sketchy and too much work. I did like Tom and went through the fender, behind the plastic liner. The toughest part is getting the liner off and pulling up a corner of carpet inside...which isn't tough at all.
Pop that US driver's side fender liner off and have a look. If you don't already have a boost gauge, Defi makes nice gauges that match well.
