...I am also adding a remote latching relay to disconnect the battery. I have grown tired of opening the boot to turn the battery off. This latching relay can handle very high amperage loads, only uses power when switching modes and is sealed. I am thinking of offering it to the auto after market. I will see how it works once all is up and running.

Plus 1 to Bob; I installed a fusible link as he did at the main loom power supply to protect the loom. This was recommended in the instructions that came with my after market loom.
I also installed a latching relay device similar to Bob's idea at the +ve battery terminal. Mine has the trade name "Battery Brain". I was Googling recently as I wanted to report on this product to the list, but their US web site seems to have vanished, so not sure of current availability. If you Google Battery Brain you can probably find some remnant articles describing/reviewing their product line, and perhaps a new site. I did find this one in the UK though:
http://www.batterybrain.co.uk/My model (Battery Brain Gold with Remote Controls, Type III if I recall correctly) even has a remote control key fob to operate the latching relay. It is equipped with a secondary connection for 'Green - Hot in run & start, fused' that senses if the ignition is on, preventing disconnection of the battery to prevent alternator damage. It is also equipped with electronics to disconnect the battery when the standing battery voltage drops to a pre-set critical level, preventing one from being left in a no-start situation. Note these last two features are both present, but you have to choose one or the other when connecting the devise.
Good product line, with models for motor homes and marine use. Don't know if they had patents in place or whatever, but thought you might find this info helpful if you are looking at product development. I recommend the product if anyone wants a battery disconnect that is reliable and easy to install and use. No more disassembly of my boot floor to do minor electrical service work!
. Was able to install in the Plus 2 without interference with the boot floor panels.
