    OK. You have a couple options. Simple and less accurate, or more involved and more accurate.

    The simple way is to just Tee into the wastegate control line from the turbo compressor housing (follow the short hose from the WG pod). Easy to access, no tooling (except installing a tee into the rubber hose), no drilling, no wrenching. However, it taps right off the compressor, so it's subject dynamic fluctuations and not a real representative of what's actually happening at the intake.

    The other (correct) way is drill and tap the intake pipe, adjacent to the intake heat element boss, clear of the end of the CAC hose connection. If you remove the intake heater and replace it with a plug, the plug can be tapped (I think Kennedy sold such an item, already tapped). Once the CAC hose is removed, I use a plug in the pipe (made from a spray can cap, duct taped in place) with a hole to accept an shop air nozzle. Then, drill and tap with it under pressure so no shavings stay in the intake pipe. Or, you could remove the pipe and drill/tap it off the engine. You'll need a 1/4" tap if using a bushing, or 1/8" if threading the line coupler direct into the pipe.
