On my 02 Audi TT Quattro I installed a Boost and A/F gauge . I have the boost working correctly and was wondering if anyone has a wiring diagram of which to tap into for the correct o2 sensor reading ..

Also I have a manual Boost controller I would like to install . I have GIAC chip on the way but would like an extra 2-3 lbs of boost while I wait for it to come in .

Any help would be appreciated .
