G60Jet 1 Posted August 13, 2003 I got my Air fuel ratio meter today from the states, looks mint anyway As you know it needs to be wired into the o2 sensor. So what i want to know is where can i pick up the wires from the o2 sensor closer to the ECU rather than fitting them under the car at the decat pipe?

Kevin Bacon 5 Posted August 13, 2003 The 02 plug is on the rear engine mount. You could always tap into it there and then run the wires through a grommet on the bulk head? Kev Quote Share this post Link to post Share on other sites
G60 0 Posted August 13, 2003 you should ground the gauge to the same ground as the o2 sensor, behind the engine. Quote Share this post Link to post Share on other sites
Toby 0 Posted August 14, 2003 http://sam.bytebandits.com/radotutorial/DSC00040.JPG I tapped it here on the bulk head behind the IM near the Brake MC (as Mkrad - VWVortex) and it works fine. Get a good ground though otherwise the gauge will do funny things when different consumers are operating (I ran one all the way to the battery in the end to be sure).
