Sorry to bump an old thread, but I wanted to add my info here as well. As Bill did, I used a TRD sandwich plate for the Defi pressure gauge and used a remote sender. Extremely easy, clean install.
I would recommend for anyone already using the gallery port as a turbo oil feed.
Just make sure to use teflon tape on the fittings being threaded into the ports on the adapter plate
Adding photos for future generations to see.

Remote sender comes from sandwich plate and goes under the intake manifold. I attached the pressure sensor to a tab on the back of the intake manifold, and have the wiring routed back to the driver's side, behind the brake booster, through the grommet in the firewall to the driver's side footwell.
