Hello
Blue wire should go to multifunction control module B9 pin, and second wire to ECU pin28. U didnt said more data like engine type and year of production so i gave you pins for petrol 1.4
Regards

Thank you I did check them and seem ok but it's still not charging customer did put a new alternator on it and charged for 2 days but they've now decided to scrap it because its value against labour time
