Having the same problem . Car dead in 3 days even with new battery . Have narrowed it down but still cant find it . The draw is diffidently coming from the 200a cable in the little black box . Unhook it 0 draw , hook it back up about .400a draw , but it does vary some . It is labeled fuse box so I pulled every fuse and still there . unhooked rcm , still there . Then pulled all the fuses at the same time , still there . With all fuses pulled , removed 200a wire and its gone . Hook up 200a wire its back . That wire feeds more than just those fuses . Any ideas ?
