OK, it's obvious you guys have not hit the age where things you thought you'd remember are remembered not. I know that if I hook up one of those disconnects I will invariably forget to switch it off on the very day that lowlife scum bag will come for my treasured truck. What I would like to have is an automatic cut-off that will cut itself off when I turn the key off, making me have to reconnect the disconnect switch under the dash or wherever when I'm ready to start it up.
