How to install universal oxygen sensor for peugeot 306?

Question

Hi guys I just bought a universal oxygen sensor for my peugeot 306. As it's universal the wires don't match with my car.

I've worked out the colours for the sensor. But I don't know the colour of the wires coming from my engine.

The colours are red, green yellow and gray.

Thanks!

You splice it in, if I were you I would take that back and get a refund and get a direct fit sensor. O2 sensor wires are not meant to be spliced.

Get the correct one for the car - you will end up having trouble if you join the wires or get the wrong.
