Hi, Looking at the Haynes wiring diagram for my 1981 series 3 the flasher unit should only have 2 wires connected to it. But looking at the flasher unit installed it has 4 wires attached to it.
The new 2 pin flasher unit I bought won't work with the Dark green and light green wires as stated in the manual.
Anyone any ideas of what the other 2 wires do 1 black and 1 brown......
Cheers Adrian Ford
