accessory

'06 Utopia 205 SE While looking through the starboard access in front of the instrument panel looking for a power source for an accessory I found this wire on the bottom. It runs aft toward the engine compartment. Any ideas

Hi - I have a 2001 Seadoo Challenger 180, I have no power to the accessories, bilge, blower, horn, radio or amp and have seen several forum posts that have said there is an 'arm' by the battery main switch, on new models, but haven't seen if there is one on the 01'.
