O2 Sensor Input - WHT to D14 (needs to be a shielded wire)
Heater Control - BLK to A6
Sensor Ground - GRN to D22
Sensor Voltage - BLK to A25 or B1 (both are 12-volt sources, so either works fine.)

These are the directions that i found what i dont understand about them is am i supposed to splice into the ecu wires with the O2 wires or to i replace the the ECU wires with the O2 wires need a better understanding
