Battery On/Off Switch
I am going to install a battery on/off switch on a TT. Where would you put the actual switch? A lot of pictures I have seen they are on the plastic case the battery sits in.

Either the hot wire or the ground wire will accomplish what you want. However, if you put it on the ground wire, you disable the breakaway brakes on the trailer, so you HAVE TO remember to turn it back on before towing. If you put it on the hot wire, that is not the case. The breakaway brakes (should) wire directly to the battery.
