This is where I would like to install the boost gauge but I started to think long term. If I sell the car with no blower then I have a hole in the dash, you never know.
This is where I tee'd into the vacuum line, zip tied in a few spots to keep it from moving around.
I ran the vacuum line under the center console and zip tied it to existing wires.
This is where I ended up putting it.
Gauge functioning at idle, still need to wire light had to break for some chow.
