good plan, after not having success with the switch installed by our dealer, our current plan takes about 10 seconds, cost no money, i remove wire off terminal, it has screw lugs, no problem. we tried the switch but to have the switch open and still try to have the cover on doesnt add adequate room between the metal so the metal services touch causing the circuit to be made even when the switch is open, maybe a bit hard to visualize but it happens, my switch was a waste of money, if it had worked it would be a nice inexpensive feature. I will probably remove it all together.
however with this said, it is a good idea to remove the wire from battery when not in use to prevent unnecessary leakage. also during winter we trickle charge about once per month.
