Autometer Phantom Boost Gauge install

when i'm running my vacuum hose from my boost gauge where do i run it through the firewall.. there is a hole my sub wires go through on the battery side of the car but if i went through there then i'd be going from my driver side pillar to the battery side back to the drivers side in the engine bay to where i'm tapping in the vacuum hose... so do i cut a hole in this and run it thriugh this? i dont see any where else it could go....

Cut a slit in the steering column boot and slide it through there. Thats one of the easiest spots to go through and your pretty much lined up to where you have to T the vacum hose.
