Bought boost gauge to go in my xr6 turbo ute. Not really too sure where to connect the T peice. Photos would be great as im new to turbos lol.

Id say closest to the manifold, as closer to the turbo will give you a incorrect reading.

I tee'd into the vac line coming off the bov. To save breaking stuff, get a length of hose the same size as what you plan to tee off, so instead of cutting into the hose, you just use one end of the old hose on one side, and the new hose on the other. You can easily put it back to stock this way.

Cheers for the help, I'll have another suss in morning.
