To run the vac line throught the dash you just use a piece of wire and fish it from the top of the dash through that side piece you opened in step 4. Then tape them together and run the vac line upto the top of the dash...
The line is coming through the firewall on step 2. It is the same grommet that the majority of other wires come through.
The gauge pod itself hide the wires and line from the back of the gauge. To hide the rest you just put the covers back on that you took off in step 2 and 4.
Please read the DIY throughly before asking questions. I doubt mean any offense by that but they are answered above....
