Hi there.
I'm assuming the flasher unit is one of the cubish things in the fuse box.
Could anyone advise me which one? I know there's a schematic on the reverse side of the fuse box cover but my cover is missing.
Thanks for your help.
It's a 1986 1.pl petrol WBX

it is a relay in the fuse box marked with nr 21 or 22 (or a blue relay)
lower right corner on late fuse box
