Where do i hook up the vacume line up at?
And for Air/fuel so i just splice it right into the wire for the sensor?

How the heck do i hook up an exhaust temp gauge also?
And same for fuel?

My friend sold me a FMIC core, 5 gauges, and a turbo timer for $150 so dont think i bought them out of nowhere lol

I can tell you that the boost guage can be "T"'d into the vacuum line that comes off the back of the intake plenum.

Those are all over the VFAQ bro. I'm not trying to bust your chops, but they are.
