Repair the Rowenta Steam Iron, model DE-283?

The iron was dropped and a blue wire in the electrical compartment was pulled out of the junction block. This model has a two piece module that controls the power functions of the iron. The junction block has four (4) spaces to transfer power and other information from the rear (cool compartment)
to the warm or hot area, however only terminals 1-3 are used.
Any wiring schematics or diagrams you could send would be very helpful.
