Side airbag light

Yellow plug is earth.

And i dont know if its the same for 306's as it is for saxo's but where the orange plugs are, the polarity of the cables switches over. SO it's not red-to-red, it's be something like yellow-to-red and red-to-yellow.

Not sure if it is the same because I fitted gti6 seats in my XS (exactly same age as his) and all the plugs matched up. Not only that but the cutouts in the plugs meant you could only plug one into one. Couldn't get them mixed up!
