tried to fit an aftermarket gauge yesterday but could not find a suitable hole in the footwell (dash) anywhere to run the pipe into the engine bay, ended up just running the pipe under the bonnet and through the window, with the missus holding the gauge to give me an accurate reading for the boost jets that i fitted, anyway as i am sure you can appreciate this is not a good permanant solution.

 

Can someone please tell me where there is a suitable opening to run the hose.

on the drivers side is the hole that the bonnet catch cable runs through, on the passengers side there is the hole the wiring loom goes through.
