E6K Diagram

The 02 Sensor should have came with instructions showing which lead does what. Have a look at the E6K diagram here.

Your 4 wire has 2 ground wires, they can be grounded together as the E6K diagram assumes a 3 wire, which has the common ground built into the sensor.

usually the wires that are the same color are your heater wires and can be hooked up in any direction. the other two will be constant +12v and the other will be signal to your ecu.
