    Can someone please tell me a spot where I can tap into to get switched power.

    *The catch is that I only want it on when the bike is RUNNING. So parking light, tail light, power outlet, stock gps plug are all out of the question.

    I don't want my sockets, cell phone, gps, etc pulling power while the bike is trying to turn over- only when the bike is actually going vroom vroom.

    This is to connect my Eastern Beaver fuse block to my 08 F800ST

    Thanks in advance

    You could try getting power from the low beam headlight feed. It isn't on until the engine starts and goes off when the engine dies. You be running power to a low draw relay that would in turn feed your EB fuse block.

    Great thanks for responding. Question though, wouldn't the power be interrupted when I switch to the high beam?

    David, sounds like this is what you need.

    http://www.motorworks.co.uk/vlive/Sh...BA_15_70_IA_75

    There is a plug under the "faux" tank centre panel on the RHS of the battery, where the above connector plugs in. The plug will be taped to the wiring form at the side of the battery and there is probably a protective cover on it if it has never been used before. You need only 2 of the 3 leads of the above connector to provide switched can bus overload protected power. No need for a fuse. Easy to figure which two leads to use with a voltmeter.

    I use it to power a GPS. This power source remains live for about 1 min after ignition off. There are many posts on this BTW.

    Eventual master of the obvious.

    I was gonna suggest that one too. In fact I even ripped the cover off the battery to go looking for it. It's there all right. You can get the plug from the dealer to insert into the jack, I think.
    Using the high beam headlights would kill the source of the low beam maybe. Anyone ever look to see if both lights are on when using the high beam?
    This jack would be the most sanitary source of aux power.

    Thanks, yes I've come across this but may have read something wrong concerning it that maybe you can help clarify...

    If whatever is plugged in (say cell phone) continues to send a signal, the stock gps socket will continue to give power?

    Also in my OP I asked for something that provides switched signal with the bike RUNNING ONLY. Having it provide power for a minute+ after the bike shuts off doesn't apply, and I think this allows power in ACC mode too which doesn't work in my best interest- trying to save all the juice possible.

    Thanks a lot for your help.

    David, the connected device, eg. a cellphone, cannot send any "signal" to keep the power on. The 1 min power timeout after ignition off is determined by the bike's electronics.
    Unless the bike's computer can be re-programmed to switch off power to the plug immediately, I don't see that it will be possible to switch off power as soon as the engine stops running. 1 minute of cell phone power draw is a negligible battery drain anyway.

    Eventual master of the obvious.

    Wally,
    Cell phone, radar detector, gps, heated gear are the things I don't want running with the alternator not going.

    Plus I already have lights hooked up that run with the parking lights (Photon Blasters rigged with blinkers and extra sets of led strips)

    Why not pull switched power from the power socket on the right side of the bike, right below the rectifier. I'm powering my Fuze Box relay from that, and pulling the 12v from the battery. When the bike is switched off 1 min later the power to the relay will shut off, opening the circuit. The power from the Fuze Box feeding the aux light relay and Hyper Lites will than be off.

    OK will try and state my request even more clear than I already have.

    I don't want the fuze block to have power if the alternator is not running. I only want power when the bike is making a VROOM noise. I do not want any of my electronics pulling power when the bike is trying to turn over. I am trying to conserve battery and letting things pull power without the bike running is a problem for me. I ride nearly every day and need my bike to start when I want it to. Dead batteries in the middle of nowhere suck!

    Thanks for everybody's help so far.

    dk, you are asking for unobtanium unless you can find a source other than what we've offered here. The two outlets are convenient and simple to get to. I would not worry about one minute of power sucking down the battery. I've left my driving lights on for quite awhile before the battery suffers.
    You accessories would not be a concern.

    In any case, I am pretty sure that power to all lights, aux power sockets etc is automatically disconnected while the engine is actually cranking on the starter. That is unless you have stuff connected directly to the battery. I think your concerns are a non issue.

    David it really is not a problem for the power to the Fuze Box to be on for 1 min. If your that concerned about power draw for that small about of time, turn you extra's off before you turn the bike off. The relay in the Fuze Box draws almost nothing.

    David, I am one of the users of the plug under the faux tank next to the battery. I've been using it for over a month to power my Garmin. It works great and no dead battery. It stays powered for one minute and then shuts off. The Garmin then asks if you want it to continue on it's internal rechargeable battery.

    OK you guys beat me up, gps thingy under the fake tank it is. Where can I get that Unobtanium from again? It'll look great against the grey.

    Also to hook into that connector, I can just tap the 3rd wire right? Or do I have to buy another adapter?

    Pricey little plug, isn't it? Just the thing to make a clean instillation though!

    The low beam wire will do what you want. The low beam stays on with the high beam so it's not interrupted. I have my Motolights wired to the low beam signal. If you tap into the bundle going to the headlight assembly, the low beam wire is the yellow one. I tapped into it at the point in line with the left hand grip (with the wheel straight).

    The GPS wire is ok too. I use it to power my GPS. It becomes hot with the key and turns off about 60 seconds after the key is switched off. However, if you want power only active when the bike is running, the yellow wire is your friend.

    Touchton, Dude, you are so right. I double checked and yep, the low beam is on all the time. Cool. I may even tap into that so I don't leave my Aux lights on to wear down the battery.

    Tapped the low beam headlight. Works like a charm!!!
    Many thanks notacop who gave me the idea
    I did it before I even read Touchton's post, I did it as far up in the headlight assembly as possible by removing the headlight. No water getting up in there!

    I found it very easy to tap into the parking light. The plug is right under the Hi Beam enclosure. The blue and brown wires are slightly exposed at the plug. You want to tap into the blue one.

    I connected my Eastern Beaver to the Headlamp bulb using a positap connector. All sweet.

    Please note to use a male/female bullet crimp connector so that when you whip the front off at any time you can disconnect without having to touch the positap. Been on mine 2 years, no issues.

    If u check my posts or search for "Denali" I posted lots of pass on how to mount the beaver

    There are three easy ways to do this:

    http://f800depot.com/bmw-switched-power-cable.html
    http://f800depot.com/can-bus-electrical-connector.html

    One uses the GPS port underneath the faux tank. One taps into the low beam. The last solution involves splicing into one of the power sockets, which is much easier on the GS models due to their being one on the faux tank. Each should turn itself off about a minute after turning the bike off.

    Hopefully that helps!
