Im looking to install an air/fuel mixture guage in my cx7.
I think there are two o2 sensors, the first one at the begining of the exhaust manifold on the backend of the motor (the one I want to hook up to) and the other about a foot further down the exhaust heading further towards the tailpipe.
It looks to me like its a 4 wire system. 2 of the wires may be for the heater and the other 2 consisting of a ground wire and the actual sensor wire. Id hate to guess and blow the sensor.
Can anyone tell me which color wire is the actual sensor wire that i need to tap into for the gauge?
Any help appreciated
