I have been beaten twice now, I have written it so sod it I will post anyway, it may help aswell
Mr self destruct is correct
If you go the relay route, I would recommend a fuse holder in the live from the battery aswell for safety sake, located as close to the battery as possible, then the only bit of wire not protected is that between the battery and the relay,
Following on from what Markie put,
If you get an automotive relay it will probably be marked up in the standard automotive notation,
i.e. the contact (load part) is between 30 & 87, and the coil is between terminals 85 & 86
so connect,
'86' to your controlling feed, side lights, whatever
'85' to ground
'30' to the battery via a fuse (and use a fuse rated less than wire!
)
'87' to your accessories
But to be honest the bits you list are low power, and will not draw much current
so a relay is probably a bit overkill
