The first layer of vinyl electrical tape is inside out, so the adhesive side does not contact the wires and make a sticky mess. This layer is covered with another in the traditional way. This allows greater flexibility vs just wrapping the wires and/or using cable ties. Usually, space in the dash is very limited so allowing for greater flex should make the installation less painful.
