    F700GS w/ trailer

    Every thing about our bike trip from Michigan to Alaska is complete except for this: We can' find anyone who is willing to wire my BushTec trailer to my F700GS.
    We are running out of time!

    While this isn't really a ride report, let's see if we can generate some help for you.....I can always move it
    I've wired a number of things and I don't know how things would tap into the BMW CANBUS way of doing things. In the old days, when I needed isolation, I would use something like this-


    http://www.towready.com

    This is essentially an isolation device that picks up 12V from the battery and distributes it to the trailer without being attached to the bike in a normal 12V drain sense.
    While I have used the older version, this kind of device "picks" a signal off say the turn signal lead using just enough voltage to light an LED. The "lit" LED has a corresponding sensor that "sees" the LED and switches the trailer light on- power is direct from the battery.
    I don't know if it's a knowledge thing or apprehension to mess with a new bike that you are running into. I don't know if my example will work but If I needed to do it, without any other examples available, I'd start with something like this. The extremely low draw may still register as a bulb fault on the dash.
    It will be interesting to see how this works out.

    I'd contact Electrical Connections in Knoxville, TN. They make a trailer converter that I used for K1600GT. Should be able to use the same for your BMW...

    Bushtec makes a wiring isolator. They are not difficult to install. The isolator is connected directly to the battery through a fuse. Then you tap into the wiring harness which puts no load on the canbus system.
