You need to route the vacuum pipe for the boost gauge through the bulkhead somewhere.
It's best to tap into the small vacuum pipe on the back of the diesel pump to measure the psi as it's the easier.
Once you decide where to put the gauge you can either tap it into the headlight switch wiring if on that side, or the centre console wiring if putting it into that area
