there's a vacuum line coming off the turbo and running up over the left side of the motor. it's about 1/8" plastic and runs under some black wire loom. tapping in takes a little imagination since the line is plastic and doesn't fit over the T fitting auto meter gives you. i just cut the plastic line and slipped some rubber hose over it and matched it up to the T fitting for now and threw on some clamps. it doesn't leak, but I'm going to probably replace the whole plastic line at some point with some reinforced rubber line of some sort so it doesn't look like a hack job.
