I'm in exactly the same boat with my coop s

, i've bought the indicator with the button but my dealers are quoting over £300 to fit it

, there are instructions for fitting a non standard button from the technical oem guides which mentions about running a wire to the speedo connector - but doesn't mention how to fit the retro unit.
can anyone help with the instructions cos it must only take an hour to fit! and i refuse to pay £100 per hour to BM, the cheeky monkeys....
