help, trying to hook up boost gauge

Can someone help and show a picture or tell me where to hook up the hose for the gauge,I tried looking everywhere and can't find anything, its just a mechanical gauge so there is just the hose for boost.

 

If its a TRD SC, from the passenger side looking in the engine bay, look toward the rear of the blower manifold, near the back corner. You'll see a red vacuum plug. Pull that off, and put your hose on. You may need an adapter to fit the boost hose to the vacuum nipple if your gauge didn't come with one.

If you look at the TRD letters, the nipple is about 3" to the left of them, just behind the coolant hoses.

 

Thank you I found it
