    I just bought the bmw part used to plug into the adapter under the front beak in order to power my gps. I'm a bit confused by the non color coded wires.all three are yellow. I'm also having a hard time finding a thread on this. Can someone point me in the right direction?

    There are small numbers on both ends of the wires.
    3 is positive, 1 is earth and 2 is unused.
    I presume you have a power adapter for your GPS, don't connect these wires directly to your GPS unless it's designed for 12v input. I have a Garmin bare wire power supply (fused), but there's also a Garmin part that is a direct USB connector with no power supply inline... Be careful.
    The connector is connected via the ignition circuit.
    Cheers.

    The OP is referring to this: BMW calls it a REPAIR CONNECTOR

    The 'numbers' of the wires are printed near the connector...about 1/4" from it...as shown in the picture.

    That's the cable with the numbers printed on it. If you look at the pictures you can just about make out the writing.

    Just for information sake 2 isn't unused, it carries a signal from the speed sensor. Very handy if you ever want to install an aftermarket electronic cruise control.

    You guys are awesome. Thank you. I guess my 47 year old eyes are getting worn down. Father Time is a bitch.

    I'm taking this into my garmin Montana cradle. Are you saying I need to put a fuse between this plug and the cradle? I thought that wasn't needed when going off that plug under the beak.

    No you don't need a fuse on that connection

    I carefully wired everything up last night and no juice. Bummer.

    I've checked obvious potential snags and am stumped. Any troubleshooting ideas you have would be greatly appreciated.

    I'm not a Can-Bus fan and a bit of a control freak. I like to control when my GPS is on and off. That's one of the main reasons I put a fuzeblock in and run my GPS off of it.

    Did you wire it to the unit to test? You won't get a signal from the pins with the canbus...

    Also - was the key in and turned on? Again since this plug is part of the canbus there is a auto turn off from the computer to avoid draining the system - so again, it will not be on unless you turn on the key and even then will auto shut-off after a few minutes (5 mins??)

    Try that.

    Did you check with a meter or test probe that you had power at the wires before you connected them to the unit?
    If not, you have the added complexity of not knowing whether it's the canbus, your connection, your GPS cradle, or your GPS.
    I metered the bare wires first so I was sure I had power and correct polarity. It worked perfectly once I connected it.
    A little more information on what you know is working and what is not might be helpful.
    Cheers.

    One is ground and one is 12 volts. Use a test light with the key on to find the 12 volt supply wire.
    Wire it to the necessary circuit for the GPS :evil The 3rd wire isn't used and has no terminal inside the bikes plug.

    Thx everyone... Duh! Regardless of how careful I was marking the microscopic numbered wires I must have had them crossed. I reconnected old wires along with touching the plug. My fuse blew so I switched my yellow wires and voila. All fixed and working with no damage. I love this site!

    On my plug, the numbers are stamped on the white plastic connector right where the yellow wires enter. They are stamped into the plastic connector, little hard to read at least for us old folks. I just connected my Zumo to that connector even though I have had the plug sitting around for about a year. I procrastinate.

    Thank you, I wasn't quite sure if that was the number or not.

    What GPS do you connect?
    I did install a Garmin Zumo 220 last year, and did run into some problems using that outlet! I guess the transformer (the 220 runs on 5V...) did fool the canbus system in some way. Anyhow; that GPS did drain my battery.

    I hooked a 220 up to the canbus and it drained my batter daily. Installed a Fuzeblock and solved the issue.
