okay question .ive had an a/f gauge and it tapped into the primary 02 sensor wire . long store gauges got stolen putting in new one . i dont want to run that wire all the way under the car to the 02 sensor is there somewhere closer near the ecu i can tap into ?or is the sensor itself the best bet?

no, dont be cheap. its inacurate anyways. get 250 and get the AEM wideband setup, das whats i did. very nice and clean

it depends what obd you are, but for a civic they are:

OBD1: Large solid white wire at pin D14 on the ecu

OBD2: large Solid white wire at pin D7 on the ecu

You can tap the signal at the ECU (which is behind the kick panel on the passenger's side). Of course, getting a wideband is the best way to measure air/fuel ratio.

if you look on ebay you can find the AEM UEGO wideband kit for 180 shipped BNIB, very accurate and a MUST if you want to tune your car
