    It will ONLY work if you have a power outlet that is hot ALL the time.
    Most of them are NOT.

    You could attach it to the fuse box terminals. Of course you would need an adapter from cig lighter to alligator clips.

    Not sure it’ll work; that outlet doesn’t have power when car is off. What does work is a power source with cable that plugs into the OBD port. It only has one or two pins, the 12 volt power ones. The OBD port always has 12 volt.

    For me that’s a JNC660 jump pack and Solar memory saver cable, both from Clore.

    Whenever the battery’s disconnected:

    1. All trip meters are reset.
    2. All radio presets are lost.
    3. Window one-touch up/down MAY be lost, need re-teach.
    4. Displays reset to factory defaults.
    5. The first start up may be a bit odd, I forget how exactly.
    6. For the next 2~3,start ups, the engine may do an unusual rev-up behaviour, some recalibration I think.

    None of these are biggies, and maybe an occasional “reboot” might be beneficial, who knows. But if you don’t want to deal with the above hassles, a memory saver is good.

    FWIW I disconnect the battery whenever doing brake work, to avoid “surprises”, not that big a deal.

    The window reteach btw, is pretty easy:

    Run window all the way down, pushin the lever down the whole time. Then run it all the way back up, again holding the lever up the whole time, and continue to hold it up, for at least a couple more seconds.

    Then one-touch it both up and down, verify it’s working ok.

    It's my wife's car...it's just easier to have the settings maintained (Nuff Said!) :) Yes, Davy and Goliath on Sunday Mornings...sort of a Gumby with a religious message, I still have the the opening theme song in my head.

    Thanks again fellas. Replaced the 6-½ year old battery with Toyota battery. I’m no lay- mechanic but it was easy.
