    You have to disassemble the lower dash to get to the back of the fuse box. The relay is on the back of it and you can block it internally or use a jumper wire.

    Yea. Add a dual battery system. Otherwise you’ll be dead in the middle of nowhere if you just use the single battery with power ON all the time. Personal experience. Won’t happen again.
