    Where is the best place to get power to power spare switch in a 389? Straight from battery with online fuse or what?

    Have you had the dash apart to look? I'd bet if its a factory installed spare switch it already has power

    No I haven't, but if it had power wouldn't the switch light up or not?

    You would think maybe, could just need to add a fuse in the fuse box
