Factory boost gauge

Aug 7, 2021
I'm gonna be swapping an LC2 in my 1982 turbo sport coupe. What runs the factory boost gauge? I'll install a real gauge also, but it would be cool to still have the dash one work.

There should be a pressure (hobbs) switch on the driver's side inner fender near the horns. It's round, two bolts hold it to the fender and would have a vacuum hose plugged into the top (sensor body might be green or black). Below is a two wire connector - try grounding each wire to see if the dash lights turn on..
