Boost gauge not working

[Benny™]

So after having all the wires under the steering column taken apart to replace the ignition switch+dimmer switch I got the car on the road and gave it enough gas to hit maybe 5lb of boost, noticed my boost gauge sat at 0, I thought maybe it was a little sticky so I held the car at what I assume was 8-10 lb for a few seconds and nothing. I checked under the column again and the vacuum gauge was still secure and not obstructed. Any ideas?

Follow the line see if it’s disconnected somewhere.

Thanks for the response, I actually already figured it out.

And the fix is?

Vacuum gauge was disconnected on the engine side of the map sensor. I was doing wiring work under the dash when the gauge stopped working, which was why I assumed I messed something up, but it turns out it was just coincidental timing
