摘要

The arrangement has a faulty connection prevention section for joining the electronic unit and connection box if they form a correct combination but otherwise preventing them from being joined. The prevention section can be mounted on the peripheral wall of the connection box or electronic unit or a nearby section; if there is an incorrect combination the prevention section and the peripheral wall section of a side part interfere. The arrangement has a faulty connection prevention section (15) for joining the electronic unit (12) and connection box (11) together if there is a correct electronic unit and connection box combination but prevents them from being joined if there is not a correct combination. The faulty connection prevention section can be mounted on the peripheral wall of the connection box or electronic unit or a nearby section; if there is an incorrect combination then the faulty connection prevention section and the peripheral wall section of a side part interfere.
