I am going to install the Gruppe S 3 gauge panel with Defi gauges to replace my stock gauge pack on the MR. Where is the best location to tap in the vaccum line in the engine compartment?

there is already a boost line tapped from the factory boost guage.. just use that one
I have the defi boost gauge - instructions are to keep the vacuum line to the defi sending unit as short as possible...
Also anyone with the Gruppe s 3 gauge panel - how do you keep your gauges from moving around?
thanks
