Normally Proton will used Bosch oxygen sensor for thier cars. I'm not sure about Waja, but Wira is using Bosch sensor.

For your case, locate where is your sensor location. Normally after your extractor/exhaust header.

Trace the wire (it should be inside the cable loom, open a bit and you can see 3 wires. White, Black and Grey. If you see different color then the sensor is not Bosch. For this case better send to the professional).


Black color is the signal wire and you need to tee off the signal to your AFR meter signal wire (normally white color). For the power (normally red wire), just get from any 12V (better used non-critical, i.e. lighter and get from the fuse box). For the grounding (normally black wire), just connect to any good chassis/body ground.

If not confident I advice better don't DiY.

Go to this website for Oxygen sensor wiring color.
