Anyone fitted one of these? The instructions came with it - in German. I'm not an idiot and it looks fairly straightforward to fit. BUT I'm at a loss as to what the 'spare' connector on the board is for. I've run the instructions through google translate but (I'm quoting word for word here) "Auxillary mass connection to the vehicle mass(removed after the ignition adjustment)" means nothing to me - unless it's a temporary earth? Why would it be a temporary earth? I've had confirmation it's not an earth, it's an additional live feed to be taken from either of the coils. Thing is if that's the case why is it not part of the loom thats been supplied? If anyone can decipher the instructions I'd be eternally grateful.
