Disconnect battery when parked?

I installed an electronic kill switch for the same reason. I know the wiring is all good in the car, went through the harness when I put it back together and replaced a lot of it when upgrading. when I had to move the battery to the trunk I wanted a way to shut it off without opening the trunk or having a visible kill switch. the solenoid has a couple small wires that run up front to activate it and keep radio memory.
