Attached is a scan of PI's parts book. It shows a relay for the central looking , not sure what side of the car it would live on, #58. If you have the wiring for the acuator in the door, you will have at least 2, most likely 4 more wires than you need for the windows and lamp, including the speaker wires if they are mounted there.
It also says there is a relay for the driving lamps in 1985. Mine does not have one, yet.
I do have fog lamps front and rear, hrw, 16-way fuse panel plus headlamp washer pump and jets.
It was going to Sweden I believe.
You might try pinging GT5-9189 who is posting pictures of his car in that section. He has the wiring attached in 2 pictures.
