Most of the power supply circuits of the electrical equipment of the American crossover are protected by fuses. Powerful current consumers are connected via relays. Protective elements are installed in mounting blocks located under the hood and in the passenger compartment.
Information on the diagrams is relevant for the Ford Explorer (U152) 3rd generation 2001, 2002, 2003, 2004, 2005 models.
In the engine compartment
There are two blocks here.
