These two installation diagrams come courtesy of GeeYouToo on the Patrol 4×4 Forums (http://www.patrol4x4.com/forum/).  This should be everything you need to know to install the TDI Boost Controller (aka Dawes Valve) and our needle valve in your Nissan Patrol.  Also, be sure to check out GeeYouToo’s  YouTube channel HERE for LOTS of good Nissan Patrol information.  Click on the diagrams to get a large, printable version.

Use our TDI Dawes Valve and our Needle Valve (one ea.) for full boost control.

Use 2 TDI Dawes Valves, our Needle Valve and our MBCS , for a two stage system

A special thanks to Chaz, who provided our original Dawes Valve installation instructions (click to go to Chaz’s page)
