I have 04 ecotec and I just got an autometer air/fuel guage. Does anyone know where the closest o2 sensor is? If so where do I tie in the violet wire(from gauge, red to switched power and black to ground)?
I have the faze guage and i put the wire that reads the air/fuel on the black wire.....works just fine....
NEW SIG COMING SOON FOR 07'!!!
the purple wire from the gauge will hook up to your o2 sensor on your exhaust manifold. if it has one wire, then connect it to that one wire, but wire it before the connector, in case you ever have to change your o2 sensor. Go to
http://www.autometer.com and into the tech section, it has a how-to for hooking up a/f gauges...
