Just been looking to see what is involved in fitting a 12S socket to my P2 V70. It already has the 12N and behind the spare wheel I can find no less than 4 relays!!
One is the one which buzzes when the indicators flash and the other three are all identical. They all have 6 wires going in, red, grey, blue, white, brown, orange. The blue is to permanent live on the battery (via an inline fuse) and the white is ground to the battery.
What are they?? There is no trace of a 12S socket ever having been fitted before.
