Hi,

I've got a 1997 ES300 V6 and the four wires from the O2 wire harness for Bank 2 Sensor 1 are disconnected from the O2 sensor plug.

The colours of the four wires are Black, Brown, Black with Yellow Stripe and Yellow with Red Stripe. Can anyone tell me which wire connects to which one of the 4 pins (Pins 1 through 4) on the O2 Sensor plug?

Thanks!
