They are aftermarket dual normally closed (NC) fused relays. Each fuse is for an independent relay circuit. Connections to the unit are +ve feed, -ve earth, Switching wire 1 to open power to circuit 1 through fuse 1 and Switching wire 2 to open power to circuit 2 through fuse 2.
They could be for any circuit on the ranga that has needed a fused relay to control it.
Id be guessing headlights +/- driving lights??? But youll need to trace the switched power side of each unit to ascertain their purpose.
Tim (Drivesafe) can supply these units which are a very neat way of running a fused NC relay controlled circuit.
