Good morning, I'm a noob here and also relatively new to the Miata. I'v been searching for an answer as to where to connect the 1/8" npt pressure transducer for a speedhut boost gauge. It's probably so simple no one has needed to ask in the past so I'll take my lumps. Could you tee into the FM O2 signal modifier under the dash with a brass barb x barb x female tee? or does the transducer need to go on the intake somewhere? Thank you

If the vacuum source is coming from your intake manifold, then it should be fine to use that.

Ok, I'll hook into the O2 line and save a firewall penetration. Thank you!
