Does anyone know how to install one of these on an ecotec, do I have to go ahead and put another sensor in or can I just splice into existing ones, and does any one know where the O2 sensors are. Thanks
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.
