My memory is worse than bad so I can't complain! I have the mirrors connected and working, as well as the electric windows, and I know which wires are for the speakers, so that clears that up.
So that leaves the white round/square multiplug as well as a black multi plug with 2 wires on it, these MUST be for the locks somehow. I think from what your saying that i have to forget about the black plug and concentrate on the white one???? It seems to have 4 or 5 wires in it from memory. I know there is live, earth, a white wire and something else that go into this plug.
