[b-13det]

Ok guys, our project is almost finished. Issues witht he boost gauge installtion. I was told earlier that the boost gauge passes the firewall. First of all, i cant find where to "pass" the firewall. 2nd, in the engine bay, i want the installation to look legit and nice. Any help will do, Thanks!

there is a hole in the fire wall where the speedometer gauge goes through. the hole should be cover up with a gromit, just cut a small hole in the gromit and run the line through the firewall into the inside of the car.
