Location of Omnistep fuse on a Duo

Can anyone please let me know where the fuse(s) is located that controls the power supply to the Omnistep slide-out step on a Warwick Duo? I don't have a problem at the moment, but I would like to know where the fuse is located in case I do have trouble later on.

Most likely under the drivers seat (you may find another couple of fuses there also)

The habitation battery and several fuses are indeed under the driver's seat, but they are not labelled and so I suppose it will be a case of pulling them out one by one until I find the right bone. Thanks for the suggestion.
