Where exactly are all the possible feed through points on the firewall?

I've been researching boost gauge positions all night and I am going for an A-Pillar mount. However there seems to be some difficulty routing things through the drivers side of the firewall and most people choose the option of going through the grommet behind the glove box.

Does it matter having that length of vacuum hose or are there ways to route it through the drivers side easily enough.

Cheers

Length of vacuum/boost tubing doesn't matter if it's small bore, Gauge might rattle, but inline restrictor stops that.

That's good to know, the gauge came with an inline restrictor so that should be fine.

I would just rather use the vacuum hose that came with it and run it through the drivers side if possible rather than buy another couple of metres which I wouldn't get until next week now.
