Aux Load Relay location

Wondered if someone might steer me in the right direction as to the location of the Aux Load Relay on my facelift RHD 1992 4.0 convertible. I believe this has failed as have lost power to the windows, indicators, stop lights, climate control etc which all seem to be routed through this relay. Any help and guidance would be much appreciated as have had a good route through both the driver and passenger side under compartments with no luck so assume it’s hidden somewhere.
