O2 Sensor wiring?


In doing my first clutch job ever (almost a complete success) I managed to crush an O2 sensor clip in between engine and trans...so it was completely toast. I got a new clip and soldered the wires for it to the wires in the truck, but the colors don't match...does anyone know/have a picture/wiring diagram for the sensor? Its the pre-cat sensor on the passenger side (bank 1 I think?), immediately off the back of the header. Thanks
