Take some moldable plastic. Use an old vent. Pattern to fit were the vent pieces are.
Cut proper hole and ut grooves cor air flow.
Attach to vent casing. Install gauge and route wires.

Here's a glitch. Not sure if the gauge will fog up or not. ???
You can create enough air flow you would not notice it. You do loose some angle movement with the gauge installed.

If there was enough interst in it. I could just make a mold to produce them out of plastic.
