hi all, ive got s2 that i very recently changed to efi ofab management. Now the engine runs fine but when i activate the rear wiper, which operates the reverse lights as i wired it up wrong and putting in reverse activates the rear wiper, need to get round to sorting that! when i press it and turn the high beam lights on loads of lights come on the dash and the fuel pump cuts out?? ive disconected loads of stuff and cannot make it any better, im thinking maybe a wire is shorting out somewhere but was hoping someone else has experienced this problem?? any help would be great!! thanks
