Just bought one of these and looked at the instructions.

The Black and Red seem easy enough but the white needs to go onto the O2 sensor.
Where can I find this sensor or even better the wires for it?
Are they under the dash?

Thanks
Scott

The connection depends on the year of yor car. Which MY is it?

Sorry Forgot to mention its a MY94 WRX

I have been looking around Scoobynet and found the whereabouts of the sensor (on the drivers side headers).

There are 3 wires coming out of the sensor, any ideas which one it has to connect to?

My instructions tell me to look at my wiring diagram but It does not say which one to connect to and I do not have a wiring diagram.

Sorry for being stupid as usual . .

Any help is much appreciated
Scott

Hi

I did this at the weekend (although not with the Dawes but the DIY version) and I suggest taking all connections from the ECU wires.

The o2 sensor is B43 pin6, power I took from the ignition B95 pin12 and GND I took from B43 pin10.

Theres a few schools of thought about where you take readings from with respect to GND points, since the difference a few mV makes can be significant. My thoughts are to keep all wires to the AFR twisted together for as much as poss, and keep them as short as pos. So I ran them to the ECU.
