Thank You very much for the information

Where can i find a diagnostic plug or connector in the fiat siena 1.6v model 2002 anyone help please

It should be somewhere beneath the steering wheel, but if your car is from an earlier production, it is most likely in the engine bay, above the brake booster. ( 3 pin connection).
