you can "T" off the map sensor thats on the passenger side theres 2 wires and a rubber hose going to it, or you can get rid of your AIH (air intake heater) and use that instead of drilling and tapping, I choose the AIH delete. you will need an adapter to fit the hmmm sorry forgot the size of the AIH to fit your fitting and your good to go.

I bet you hardly use that AIH . . .
Maybe you got a vacuum gauge? Anyway, you can either drill and tap the spider or just tee into the MAP sensor line like stated.

You guys know there's no vacuum there - right?

The whole system runs on pressure...
