View Full Version : How to hook up Air/Fuel gauge? screamin R6 02-09-2008, 10:24 PM I got a used air/fuel gauge from a guy but didn't get any directions as to where to hook up the wires. There is a black, red and some other color. Where do these go to? I am assuming the black is ground, red is power but not sure where the other one needs to tap into the oxygen sensors. Any help would be great!! screamin R6 02-10-2008, 12:03 PM Anybody know which O2 sensor I need to hook this wire to? Any help is appreciated! 99_Z71 02-10-2008, 01:10 PM If you have a wiring diagram of the ECU tap into the O2 wire, that's what I've done with all of my cars. Or you can tap into the the sensor right at the exhaust. S/C Z71 02-11-2008, 03:19 AM Get a wideband. vBulletin® v3.8.2, Copyright ©2000-2009, Jelsoft Enterprises Ltd.
