Air Intake Heater?

[Big Calo]

I have a Early 99 and I thought that it didnt have an AIH. On the spider there is a brass plug that has two wires coming out and a red boost line that also runs to the waste gate. I am going to be putting guages in this weekend and was wondering if this is the AIH where I can plumn the boost guage into, or is there a better way to plumb it in?

Thanks!

Those green and red lines are vacuum lines for opening or closing the waste gate actuator.

That line is the one going from the 90 degree nipple off the spider to the MAP sensor. You can tap into it if you want.

Its not that one. it is a brass plug located to the right and lower than that one. There are two wires and a red hose coming from it.

Yea I know it's an early one.
Either way, find the line that runs to the MAP sensor and tap into it
