Wiring mains charger to leisure battery under bonnet of Crafter

[wanderinmac]

Hi all trying to get leads through bulkhead to access leisure battery which is fitted under the bonnet but cannot see any easy route or access point. Would it be possible to connect mains charger to electrics under passenger seat as there is a fuse box and other electronics there supposedly for leisure battery? I dont have wiring diagram for leisure battery so not sure what all the wiring under the seat is for. Any help greatly appreciated
