It is an auxiliary fuse box, however it is related to the CCRM only in that it is the fuse for the engine cooling fan low speed operation--it is wired "after" the CCRM, between it and the low speed ballast resistor (not shown in the diagram as it is considered an integral part of the fan assembly)--here is the wiring diagram, see points "D"
It is mounted in the fan shroud.
It is there because if in low speed operation the cooling fan motor were to short it could draw a whole bunch of current and perhaps start a fire. The ballast assembly (see below) consists of a big wire-wound resistor and a thermal fuse, an almost redundancy in case the resistor gets too hot.
