sorry to post in this site. i have a 240 w/ca18det. im using a 3 wire bosch 300z tt o2 sensor. i have one blue wire and 2 black wires coming off new o2. could somebody that has put one of these in tell me which wire is signal and which other 2 are the heater wires.

much obliged.

I believe the blue wire is your signal and one black is hoat and the other ground, I don't think which goes where matters as they simply power the heating ballast in the sensor, the blue wire si th only one that matters
